Anyone help?

This is a real issue for me.
I've managed to get the script to allow payments, however on return to the site and it says payment sucessfull, it shows the ammount of time added to users account but once you login it shows up as account expired.

For some reason it is not adding any information to the database after sucessful payment has been accepted.

I have currently had to turn of the package feature because of this.

Please can anyone help?

Regards,
Mathew.
