Cd-rom Cd-writer vanished!

[Akifon]

When i installed clonecd 3.2.1.1 i restarted my comp and saw that my cd-rom(philips 36x) and cd-writer(plextor 8/4/32A) are vanished!
I tried reinstalling the drives, i uninstalled clonecd and installed ASPI drivers from nero but it still dont help.
In device manager it says that the registry might be corrupted!
any1 have any clue what the hell i should do???
Earlier versions of CloneCD worked just fine with my burner but this..

btw: my OS is Win2k Advanced Server
