This is a long shot, but if anyone can help that would be great. I have Logic Audio 5.5.1 for PC, purchased in 2002 (!) as part of a 'big box' deal. I have now replaced and upgraded my computer. On reinstalling Logic (first 5.1.3, then the 5.5.1 upgrade) and plugging in the XSKey USB dongle (which I know works with the old PC), unfortunately my new PC says 'XSKey communication error' when I try to run logic audio! I don't understand why. I'm running windows XP. Grnaaaaargh! Can anyone suggest anything to fix this? I don't want to feel like I'm chucking away 200 quids worth of decent product. Many thanks Dave
