Carrington Theme has completely changed my website

I recently updated Carrington Blog Theme from 2.0 to 2.2 and i have noticed that my website has been completely changed and it no longer resembles anything close to what it looked like before.

I managed to obtain version 2.0 again, uninstalled CBT and then reinstalled and activated version 2.0 but im still having the same problem.

Am i missing something? im not sure what went wrong in the first place. I updated to wordpress 3.0 last week but the problem i had with my layout only cropped up a few hours ago.

Anyone be able to help me? Pleaaaaaaase!
Thanks in advance ??
