I am also having problems loading the Seasons Starter Save game (Union Cove Seasons .sims3)
I have Generations, Pets, Seasons and Supernatural, no other expansions.
I have downloaded the full world and verified that it is selectable in the drop down for "Select a Town" when creating a new world.
I have downloaded the save game and verified that it is visible among the list of other saves.
I've done a "factory reset" (deleting my docs\ea\the sims 3 folder completely)
When I try to load the save game, it gets to about 40% complete freezes, my drive is busy for a while but that could just be standard drive noise, and then I get the "A serious error has occurred loading .... " which is of course absolutely perfectly helpful and informative.
I've gone over this thread and seen other people having this problem but haven't seen a solution (which may be a testimony to my reading skills). Is there one? Have any of the world builders seen this issue?
System info: Win 7 64 bit, 4G ram, GeForce 9500 GT
Thanks in advance
