My big mistake was installing v3.4 final? I thought! So on reboot I got this error message->error in initialization check user dcuserprot.exe. So I searched the forms and did what Gavin said in his step-by-step removal and tried it 17 times now or more and still get this error! Also tried version 3405 and the App. hung and Windows would not load. Went back to version 3.150 and got this error->pgaccount is not running checked the forms did what Gavin has said(step-by-step)and now I can't use any version of PG! So as a last hope of getting it back used Norton ghost v10.0 every file was perfect and in place except PG was blue,opened it up and it just had a main screen,nothing else and got an error in opening mutex2. Searched the forms again and did not find a solution to get PG back and running,but nothing works!Please keep in mind I know how to install and uninstall this program correctly,and removing the files left over files are deleted in safe mode.(followed Gavin's step-by-step all the way)also uninstalled every program at start up and still get the same errors,so if it's not a driver conflict what is it? If anybody knows how to fix this error that would be great,I have given up hope after 48 hours! Thanks in advance.
