BIG trouble dont know if I am Fried!! HELP

After like 6 months of working on my forum and adding numerous hacks, everything was perfect, 600 users, a lot of visitors 15 registrations minimu a day and 3 new sponsors that i signed a contract for adds this week, everything perfect then murphys law becam e efective...
You see my Hosting company has been bugged by me because the FTP access is very dificult from my account so i did thing very slowly etc etc, yesterday I made a backup of my database, and accesed de FTP part of my Vbulletin software, I changed some parts and the session died (has has been disconected many times before) and when I reenter my forum folder is GONE, I almost passed away at the sight, even my wife said I was pale, took a deeo breath and quitted the ftp program re opened it and yes the folder is GONE also with another parts (less important).
So my situation is:
I have a perfect mysql database (not deleted) and a backup.
have no forum software....
maibe I am Fried but :
If I reinstall the Vbulletin software how do I reattach it to the databse?, will it work? does it have to have the same hacks installed to work, any hints ideas etc woul be greatly appreciated, cause you are almost reading a dead man walking!
:ninja: :surprised:

Yes. Threads, users, forums etc. are stored in the database.

Also, I would suggest making a couple back-ups of the database
