I really hope someone can help me this time. I have both Akai and E-MU sounds stored on my F drive. Converted them to giga format with Translator Pro. From the instrument loader pane I try to load one and get the prompt:Unknown system error. Would you like to continue loading this performance? I click yes, it shows the bar then disappears without loading. I've uninstalled everything on the machine except the essentials, re-installed both GS3 Orchestra and Sonar HS, repaired the files on the F drive, a Western Digital 149 gig. Re-installed the Audio Delta 1010 with update. Uninstalled Translator. Disabled all audio except legacy and GSIF2 in the Delta. Could it be an IRQ problem. Don't know much about that but didn't have that problem before. All the regular giga files load just fine. It's just the converted ones that don't, except a small few that will! I can audition them all. They just won't load! Oh great and powerful Oz, please HELP!
