Thanks for your response. Last night, through "Teamviewer", James tried his best to resolve the problem. Then he got an outfit in California to go into my PC and try to work out the fault - no joy. Then the "ones & zeros" guys in Taiwan last night (late) went through my system and they too were unsuccessful. After reading your response I immediately un-installed the software plus went into the registry and deleted all it's fingertips then shut the unit down and removed the card. Rebooted PC twice then re-installed software (for 20th time), again re-booted twice, shut down and re-installed the card. Fired back up and experienced same issue. I've asked James to consider a replacement card & software as I am getting a little tired of screwing around with this thing. I may not have much of a life but I'm sure I can figure out better things to do than spend another 20 hours fussing with this software. FYI - I originally had Vista OS but the Nuuo card was not compatible so I changed to XP Pro which I've been wanting to do anyway - just needed incentive.
