Very big problem with db

[jukesoft]

Hello! I have another problem. On my host i have 2 databases: one for SMF forum and  one (itforum_test) for testing various scripts. The problem is that for the second database i've made a new user with the sane name as for SMF's database. Now, when i acces my site, i get: 

Connection Problems
Sorry, SMF was unable to connect to the database. This may be caused by the server being busy. Please try again later.

That's because the database user was "reset". What should I do?

I've solved it.....so quick. The problem was the password(i've changed it.)
