I have two separate problems, but I will put them together in one post. I've been posting on other similar threads but I haven't received any answers so I hope this works better.
Background: Right before Patch 1.50 came out (I didn't know it was going to come out or I might have waited), we installed a new operating system on the computer. The reason for this was that we bought extra RAM to bring it up to 10GB but the OS we had (Windows XP) would only work with about 3GB of RAM. My husband told me his friend said we needed a new operating system in order to get the full effect of all the RAM. Since I was very tired of my game crashing and getting Error 12s I was really excited to have more RAm, since I was told this should fix those problems.
When we upgraded the system I re-installed all the Sims 3 games. I had to patch in order to install any expansion packs. I don't know what broke my game, whether the patch, the new OS, or something else, but I have since un-installed and re-installed three or four times and nothing is working. Last time I even did a manual un-install, which took forever, and it still isn't working.
Problem #1: I can't open any save files.
I opened my game as normal, selected a file and waited for it to load. It got almost all the way done loading and then I got a message saying: "A serious error has occurred while loading Sunset Valley.sim3. It is strongly recommended that you restart the application." I thought it might just be for pre-patch save files, but when I created a new file using some saved houses and sims from the library I had the same problem. So I can't open any save files.
But on my last re-install, I thought "let me check after I install each expansion and see if I can open a save file so I can pinpoint the problem". I opened a fresh file in Sunset Valley, selected the Working Friends household, and saved the game in Live Mode. I then quit the game and re-opened it. For the first time in over a week, I was able to open a save file! I got a little excited. But then I installed several more expansion packs, forgetting to check in between. After I finished the one I was working on, I decided to check the file again. I was able to open the base game save file again, but I decided to add some content from the expansions to test and see if that was what was affecting the game. I added a dining chair from each expansion I had added and saved again. When I tried to open that save, I got the same error message. Thus I think it is the expansion packs that are causing the problem. Trouble is, I don't know if it's one or all! The EPs and SPs I installed are Fast Lane, Generations, Pets, Showtime, Katy Perry Sweet Treats, and Seasons.
Problem #2: The Launcher has stopped working.
I have seen many people on the Internet with this problem but none of their solutions have worked for me. Yes, I know the workaround on how to get into the game without the Launcher. I also figured out (thanks to a thread here) how to install content without the Launcher. I even managed to patch without the Launcher. The thing is, I'm just funny in that I like my whole game to work pretty much all the time. I'm particular that way.
So this is what I have tried to fix my problem: I have done a complete uninstall/re-install. I have done a manual uninstall and a re-install. I have done a factory reset (seemed redundant with the re-install but I did it anyway). I have removed all CC. I have patched. I have updated Origin. I downloaded EA Download Manager, which is really hard to find now. I turned off my Internet (that was a suggestion somewhere). I restarted the computer. I cleared caches. I made sure nothing else was running when I ran the game. I deleted the file "missingdeps.idx" from DCCAche. I have installed all the EPs and SPs in order. I have done them out of order. I have done them in backwards order. All to no avail.
There may be more I have done but it's all running together now. The point is, nothing has worked yet. If you have suggestions, please let me know and I'll either try it or tell you I've already tried it.
Edit: I am planning on getting University Life (and praying that it will fix my game if nothing else will) but I can't afford to get it until it goes on sale.
