Coppermine is in db_forum_gallery
and the forum is in db_forum

Two seperate databases but same login for both.

What could be the problem?
Thanks!

Right in the briding instructions it says that both apps must use the same database.  merge your databases.

No you don't. See http://forum.coppermine-gallery.net/index.php?topic=28263.0

In 1.3 they need to be in the same database, for 1.4 they don't. The code differs between versions which is why the support sections are separated.
