TSSTcorp DVD+-RW TS-L632H Device not working

Okay so I own a Dell insporon 1525 Windows Vista 64bit and I have fixed this problem previously, and for a short while it worked, but now its back to the way it was. I have Itunes downloaded onto my computer, and I know about the filters that it puts onto the drive, but since i had it fixed before i figured i could A) fix it with the same program i fixed it with, B) Fix it manually or C) maybe swipe itunes from my computer, which would suck it would be like throwing away 500 dollars worth of music and it wouldnt help me anyhow i wouldnt think. So I tried step A but that did not work because i am broke and couldnt buy the full program that fixed the problem previously. So i tried step B, but to my surprise while following the steps for windows vista to manually deleate the filters, the filters where no where to be found under
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Class\{4D36E965-E325-11CE-BFC1-08002BE10318}
which sucked royaly, because now my only option is to delete Itunes, and i dont even know if that will help me, besides that the only reason i want the drive to work, is so i can download my music to Itunes.
Please help me?! n_nU
