Alright then, I have a simple probards webbie that I set up, quite simple really. Well, I had the settings programmed so that I was the only one who could change my settings or details or profile and whatnot. Well, my name kept changing along w/my info, and I finally found out that it was one of my friends who did it. He told me that he installed a hacking program so that he could change it. I begged him to take it off, and he said he did, but when I checked later, my name was changed again, and it logged me out and I can't get back in. I have another screen name on the board though, and would appreciate any knowledge of how to stop the hacking program or download an anti-hacking one for the proboards website (preferably free ones.)
If I had to guess, your friend probably found out your password. I've seen this happen before. One thing that you might have overlooked is when you get it back, make sure your password is being sent to YOUR email and not your friends. (you know, the "forgot password" e-mail. Also, if this was a primary password, I would change all my passwords just to be safe. Hope this helps.
