it is possible, but....it is more likely that the pinnacle software is the source of your troubles. buggy burning software that casues conflicts can cause all kinds of problems with optical drives. a prime example is earlier versions of easy Cd creator which was notorious for disabling burners or making them disappear completely from Windows.

Do you have other burning software installed besides the pinnacle software?

i have Nero Burning Rom and Cute CD DVD Burner...i did download alot of other ones before but i uninstalled them all (including the easy cd creator u said, but this was a couple of years ago)

it could be that pinnacle is not playing nice with the other burning software. this was the problem with earlier versions of Easy cd creator. unfortunately most people found the only way to fix their problem was to reinstall windows. it is possible that your burner is defective. if you have the opportunity it would be worth your while to install it in another machine if available, this would tell you if it is a burner problem or a software problem.

for the hotfixes....how can i download the missing hotfixes on my computer? because i deleted some of them by accident before

Go back to Microsoft update. if update does not detect those updates it will offer them for download again.
