My Forum Dead (many QUESTIONS) ... Please HELP!

[محروم.كوم]

I need your help. I had a 3.6 and I recently changed my web hosting company, long story short; can't successfully upload vBulletin into my new FTP, so my forum is officially dead.

Here's the link to my forum: http://www.jimmy540i.com/forum/

How can I get my forum back? Please point out a place to talk to any vBulletin representatives in this forum.

Also can I do an upgrade (Eg. 4.0) since my last forum was attacked by bugs (filled with porn sites) before I changed the web hosting company, how much does it cost?

Also when people click on the link on my forum, it turned out to be a page like this:
================================================== ==================
Database error The database has encountered a problem. Please try the following:

• Load the page again by clicking the Refresh button in your web browser.
• Open the www.jimmy540i.com home page, then try to open another page.
• Click the Back button to try another link.

The www.jimmy540i.com forum technical staff have been notified of the error, though you may contact them if the problem persists.

We apologize for any inconvenience.==================================== ================================

How can I turn the URL to my website (http://www.jimmy540i.com/forum/) into HTML before I fix the forum?

MANY, MANY, MANY thanksss!
