vBulletin troubles!!!!!

[Complicated Guy]

I've got a trouble with my recently-installed vBulletin Forum (version 2...).

In all the forum pages appear a message above and by the way I can't acces to the administrator control panel, the problem is something like this:

- I put my nick and my password in the admin/index.php page.
- Then I'm take to another page that say "Hang on a sec"
- Then appear a "Not fin the page- Error 404"

Help!!!!!!!!! Please!!!!!! I'm frustrated!!!!!!
