Crap, Forum not found problem?

[Suke]

Well, I had my Smf 1.0.7 forum, and I backed it up and all, then I went to upgrade it by extracting Smf 1.1Rc2 into teh same folder. But then after uploading it, it did'nt work. Now I put teh old folder back over it, but it still does'nt work.

Jeez, what did I do wrong? How can I fix it?

Nevermind, I seem to have fixed it for teh moment...

Edit:

It says I'm not online to all teh members, and when I goto my forum it says there are no members and no users on >.<
