Registration Problem

[AuroraStorm]

When I signed up with vBulletin, I had tons of problems, among them uploading and whatnot. I was using 3.5.6 because I didn't have enough MySQL or PHP space while using GoDaddy. Because I had everything uploaded in the original install incorrect, the board eventually crashed, which I didn't expect it to go smoothly and am very suprised it didn't crash sooner but anyhoo, a friend moved me from GoDaddy to his server and upgraded me to 3.6.4. Of course I lost everything and had to start from scratch. My members had to re-register but for some, when they tried to the system told them that the screen name already exists but it's not in my new username database. Is there a way for me to retrieve the old log ons and if not, how do I get past this problem with the registration of the members of the previous installation?

Hopefully this is in the right forum...

The only way you'll be able to recover the old information is if you have the old database which it doesnt sound like you have.

If you used a clean install of 3.6.4 on your new host, and its telling you the username is already taken you're friend didnt install it correctly.
