Trying to use Primo but didnt work...

[rubber2k1]

Used Primo to backup Hotshots Golf3. Went by the Primo guide by Charlie. I'm using Memorex media and the famous pioneer 104 with the px engine upgrade and the firmware upgrade. When booting it on the PS2 it gets past the PS logo but either goes to the 'Please insert a psx or ps2 game" or memory card screen. Not sure what happened. It said it burnt it successfuly. it does play cd-r backups without any problems. any ideas?
