Well, I can't use my old username (Rose Flame), but my comp finally let me back on. I'll post what I did here, and maybe it will help someone here having problems.
Okay, if you have AOL like I do, than it's a little harder to work out. You have to find some way to open up the normal internet explorer after you've dialed up with aol. Then you go to tools, internet options, and then click on settings in the general tab. Once there, you have to delete all cookies with the pokecommunity on them. If it's like mine, it won't let you delete a good many of them. After that, shut down your computer, and then turn it on again. Then, if when you dial up for AOL, a box pops up that says that AOL will need to restart your computer, click okay, and restart it yourself. When it has, dial up, and it should work.
I don't know if this will work for anyone else, but it did for me. Hope it helps.
