Difficulty importing phpbb backup

We’re looking to completely move a phpbb from SlowDaddy however we’re having difficulty getting the backup to import into a fresh install of the same version of phpbb. During the first attempt it returned a message saying it was waiting for www.fzr1k.com/phpbb/ad,im/admin_db_utlities.php?sid= (a really long string of numbers and letters) and then timed out. That was from my friends system in Seattle. I downloaded a copy of the database and tried it myself and didn’t get any errors at all but it didn’t import it either. The version that we’re using is 2.0.15 and we’re hoping to upgrade it to 2.0.22 though this was the testing installation for both migrating away from SlowDaddy and doing the upgrade. Any recommendations deeply appreciated.
