I can't really help you without a log, if your username for anything is your full name then maybe you should change that.
If you know how to use find and replace I suppose you could do that.
Possibility of Malware, taking money(e.g. ad revenue) away from the devs, and pushing old versions as if they were current are the most common problems with sites like that.
DO NOT use that website.
Please read up on the StopModReposts Project, delete all files you got from that site, and get them from the proper source(s).
