I've just tried to access the gallery again with no luck. It continues to see me as a guest and won't let me access my albums. I don't know what "the control + F5 forced refresh" is (from Carl's post). How does that work, or is there something else that I can try?
For F5, when you are on the web page, you push F5. That is similar to pushing the browsers refresh button. You may need to push a function button or control + F5, depending on how your keyboard is. You will now when it works though, the page will reload.
I would try using a different browser if you have another one on your computer. I personally use Google Chrome. When Chrome doesn't work I try to remember to jump on Internet Explorer to see if the website works there. After trying that, I would clear your internet cookies. A little clean-up might help.
I was having trouble accessing a website last night. I did all of the above but to no avail. Carl even tried. He was successful loading the website, where I wasn't. I can now access the website fine now, but it did take awhile.
Good luck.
