So, My host is 000webhost. I downloaded SMF 2.0 RC5. When I got to step 2(Database stuff, username, password, server name, blablablablabla). I entered all the correct info, and it said this:
!!
Critical Error!
Cannot connect to the database server with the supplied data.
If you are not sure about what to type in, please contact your host.
Access denied for user 'a3074591'@'srv40.000webhost.com' (using password: YES)
Now. The weird thing is, the host I entered wasn't srv40.000webhost.com. It was server40.000webhost.com.
Here's some pictures, please review and help.

This shows the errors and text boxes within the SMF installer, and the info from 000webhost.
Thanks. Ends up there was a preset for SMF. So it made it much easier. But thanks anyways.
