DVD CD/RW Drive goes AWOL

[Brucey]

After installing Video Hoster v 3.310 on to my laptop the drive disappears from the windows xp system. In My Computer\Hardware\Device Manager it shows an exclamation mark against DVD/CDR drive with error message as Windows cannot load the device driver for the Hardware, the driver may be corrupted or missing. I reinstalled the driver and got the same error message. It also does not show in Hoster. After a system restore to before Hoster Installation the drive reappears.
I have checked the the ASPI driver and that is correct version @ 1.27f. I have reloaded sound, graphics and chipset drivers to no avail. All drivers and Windows software is totally up to date with no other programs loaded.
Any ideas on a solution to this problem
