Error Code 108 displayed on starting Sandboxie

Hello All,
I am using Sandboxie and while trying to play the game Digimon Masters Online which requires hackshield to play it gives a hackshield initialization failed error and terminates. It says an error occurred in the hack prevention feature. The error code is 108. I am using a pc with Windows XP service pack 3. I was using McAfee VirusScan in my pc. I uninstalled it and tried launching Sandboxie. But this did not fix it. Can anybody help me please? Thank you for the replies.

_AhnHS_Initialize : [H:06]An error occured in the hack prevention feature. (Error Code = 108)
The program will be terminated.
