Thanks for the help

there must have been a third reason why this was happening. I did have both tables within one datbase and the prefix is definately "smf_"
I tried doing this from scratch again on a clean installation of the latest phpbb2 version. But it seems like phpbb2 does not work properly. After I install it and try to login as admin, phpbb just keeps redirecting me to the login without even giving me an error.
I was able to convert from smf 1.1.3 to phpbb2 but phpbb2 does not function since it does not let me log in. I am trying to login with the new phpbb2 admin login that was created when I installed the forum so I don't see why there could be an error. Could this be due to an .htaccess file that might be missing?
