SCSI's not working? Daemon tools updated?

Hi! Sadly I updated my Daemon tools Lite recently, which proceeded to screw my computer up. I have unusable virtual drives that I cannot make go away. I have tried Device Manager and deleted them but after reboot they come back. Another problem ( I have reinstalled daemon tools after ) is when I go to add VD's nothing appears. After several tries it'll say my computer has no room for VD's. So I'll reboot my computer and TAD-AH! We have all the old VD's back. I am unable to mount my image files to them so they're completely pointless - windows says their operational but eh. I was going to reformat my computer, but now I'm missing my Windows 7 Disk... So yeah. Any help would be appreciated! A step by step tutorial on some guides would be EXTREMELY helpful. If it works then I'll chose yours as best answer of course.
