From what I know so far, find and delete all of these files (if they exist) from the start menu/find command:
bm_insta.exe
bmail.exe
CD_Load.exe
createsw.exe
driverpg.exe
istabm.exe
delete the files from the find results and then restart your computer. You shouldn't get the driverpg error anymore. That's what I did and I haven't received the error message again. Hope this works and gets rid of any problems you may encounter... if not, best of luck.
