Check that you entered a comma delineated list of the usergroups that can access the script (1,2,3,4,5,6,9,10 is what I use) , and that you uploaded gwowroster.php to the correct location.

Run the main cron task. Post the message it gives you here (e.g. it told me it failed to parse originally, when it went through successfully it gave me a list of what it updated.) Ignore the talent parser bit, you want to fill the roster.
