Aright guys, heres the deal

i had to reinstall WinXP over an existing install of WinXP cause my computer got destroyed. Now, and i'm assuming this is related, the BBS is giving me issues. The BBS will let me login, and it'll take me to "My Home", but when i click on Main Index or anything else, it immediately logs me out. So basically, i can't tell which posts are new, and i can't make posts. I have cookies enabled and all my other settings in IE 6 are the same as i had them. Actually, i reinstalled IE for the hell of it. So what happened?
