[ClActLitigator]

I have tried a number of the fixes (all listed here and from other forums), and I still don't have sound. I have 2 devices that are error'd (yellow excalamtions). AC '97 and MIDI, respectively. This happened after installing and experiencing major issues with virtual cam (splitting) software. All of the trash/junk associated with these programs has been removed. After extensive research on many forums/threads I am certain this is related to my plug and play enumerator. I've attempted system restore/config, checked system admin and services are fine and automatic. I've attempted rollback to previous drivers to no avail. I've corrected and reinstalled machine.inf and swenum (Drivers) respectively, again, no avail. That said, I'm certain this is registry related, especially because of the blue screens I rec'd after initially installing and attempting to operate the malicious nazi software. I'm confident I can remove the upper and lower filters as described in many threads, however, I'm not sure of what registry keys to do this on. The only keys I have found in threads, etc are related to peripheral devices, CD/DVD rom's etc. Are the keys the same or do I need to correct other ones specific to my issue/device?? I'm desperate, can anyone help me please for I will be eternally grateful!
