Nightstalker

I have had an issue for 4 weeks with this HOTAS. The throttle has had calibration problems since purchase. It took me two days to calibrate in the first weekend I purchased it. It wouldn't calibrate in the windows setup or in the HUD software. After two days of frustration for some unknown reason it finally calibrated in windows and then calibrated in the HUD. It worked for a week and then the next weekend the same problem started again. No throttle, unable to calibrate in windows or HUD software. Again spent two frustrating days removing/installing drivers /software trying to calibrate etc. Turned on the computer second day tried one more time and like the first weekend it all of a sudden calibrated. I have enjoyed this HOTAS for two weeks until yesterday I was flying and having a great time and got up to get a coffee. Returned to the computer, fired up another flight sim and bam! No throttle. Suddenly unable to calibrate in windows or HUD again! It has now been another weekend of frustration following Saitek's instructions of removing and installing software. VERY FRUSTRATED. If you turn down the lights on the HOTAS through the HUD software you will notice that the mode switch lights on the throttle will still light up to indicate what mode you are in. Mine is not lit up now. Is anyone having similar frustrations? Why is there no customer service at Saitek on the weekend when most people are needing assistance?
