Okay temporarily back on. My dad suggested I use AOL to try to access this site, as it is our second ISP. Our primary one is Prolog. It seems I can access this site just fine with AOL. But not with Prolog, so that's where the problem lies, probably.
I'll make this clear. It is not a problem with my computer. If it was, shouldn't I still be able to get on using the Wii and Clint's computer? Both are unable to connect to the website, leading me to believe it isn't a problem with this single computer at all.
As for the post/account deletion, that is a misunderstanding. There were two support boards they had provided, both with a similar appearance. I had tried to log into the wrong one, which gave the illusion that my account was deleted. It's still there, Malte's account is still there, the posts are all still there. And they haven't been locked or moved.
Anyway I should probably contact Prolog somehow and tell them what's going on. Until that problem is fixed, I can only get on Gang of Five via America Online. Good thing my dad didn't get rid of it yet.
