I posted on PHP and I feel may be I post on wrong place

I have been using WAMP to setup my forum (PHPBB3) and and a site. For some reason I don't know, PHP installation of WAMP was crashing with message can't find logger.dll. I removed my www directory and uninstalled WAMP and re installed, that is when I knew that I forgot to bakup my databases. I used system restore and cannot access the database

Any help or suggestion? It is painful to start setting up forum again, due to limitation in time! Pse help

At this point it's data recovery, not PHP, Windows software (WAMP) or even Vista. Stop using the drive, research data recovery and "undelete" from another system, and see what you can come up with.
