Hello, I installed PG Free in XP Home yesterday afternoon and everything seemed to be working fine. I then decided to purchase a licesnse that night. The next morning I installed PG full. First, I restarted the computer into safe mode and ran the PG Free uninstaller. I checked the system32 directory for any leftover traces and only found pguard.dat so I deleted it and restarted. I then ran PG setup and it told me it needs to restart, but before I did that I extracted the pgkey.zip file to the PG program file directory and clicked ok to restart. PG seemed to be working fine in learning mode and after a couple of minutes I restarted once again. This time PG started and all the protection was disabled, so I enabled everything but nothing seems to be working. The log is not recording any program activity. The only thing the log recorded was [1 of 2] Failure: Driver is not correctly installed or active. [2 of 2] Failure: Process Guard's Protection is currently disabled. Enable it in the Protection menu. The rest of the log just lists the enabled protections I set and all other functions seem dead.. Any advice or help would be greatly appreciated. Thanks. Update: After restarting again everything is now working.
