I was trying to get my Tsst DVD to work, driver detective gave me instruction to turn off the filter. I got confused and deleted 3 upper filters that situation went really bad. Now I can't use keyboard or mouse. Tried to reload Windows XP to do a repair, no way to comunicate with computer! Original-went to regedit, found 4d36e965-e325-11ce-bfc1-08002be10318 found it deleted upper filter, went back to list thought i found 2 more deleted those upper filters then discovered they were not the same. Too Late! any suggestions?
