Installed Vogone - lost both CDROM and DVDROM drives

[dcarwin]

Update:

1. Uninstalled Vogone - drive letters still missing, drivers still corrupted.

2. Started googling the error

3. Found this obscure registry hack:

Start Registry Editor (Start, Run and type in regedit then click)

Find "UpperFilters" and "LowerFilters" (and "UpperFilters.bak" "LowerFilters.bak", if they exist) value under the following key in the registry, and delete it:

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Class\{4D36E965-E325-11CE-BFC1-08002BE10318}

Quit Registry Editor.

Reboot.

4. After reboot - the drives are back! (w00t)

So now, the question is, was Vogone responsible or was this just a coincidence? One way to find out...

5. Re-install Vogone (requires reboot)

6. Drive letters gone again!!! Drivers corrupted.

7. Leaving Vogone installed, I perform the registry hack above and reboot.

8. Now I have my drive letters back, and Vogone installed. Hopefully the system will remain stable.

Conclusion: this is a very serious bug. Any support reps lurking/trolling the forum?
