Install problems

Hi,
I cant get open cart to accept my data base info

I have uploaded open cart to my server,
chmod required folders and files,
all green boxes are checked in step 2
but in step 3(http://mydomain/cart/install/index.php?route=step_3) i cant login to database correctly. I use exact database details given to me when i set up the database and can login to data base with those details.

Im stuck.. and dont what to do next.

If anyone could help.. it would be a great help

Please!!

1. which webserver
2. which versions of
2.1 apache
2.2 MySQL
2.3 php
3. database running under localhost or else (host)
4. user & database name should be clear
5. prefix needed only if you want it, otherwise leave it empty
6. the database MUST be already created
