I have my Old DB which was taken like a month ago and i have only DB no Files of it and when i tried to upload it its uploaded but i can't see any kind of Index or login page every time i open them they just show the adressbar at title so that's the reason
When you say "no files" do you mean you dont have any vbulletin files?, you need vbulletin core files with the proper settings in your config.php in order to view them.
You cant get files if you havent got a back up of them, you could ask your hosts if they have a back up, other than that you're starting from scratch with a new download from vbulletin.com!
