Most database problems turn out to be application problems (I've been a DBA for best part of 10 years, so feel qualified through expereince to make such a generalisation
)
If your admin logon works, then you're going to have to put some debug logging in place so you can see the SQL you're actually sending to the database and what the response is.
Is it your script ? If not, then I guess the quickest option is to go back to the author and ask for help.
