I installed MSS about a year ago without error. I used it a couple times without error, until last night. When I plug in the Stiletto 2 I get a "Device Failed Connection" sound through my speakers. (Double beep) The computer will not recognize my Stiletto. I thought something was wrong with my unit until I installed MSS on 2 separate laptops without a problem. When I plug in the Stiletto to either of the laptops it is recognized and I'm able to transfer songs. My desktop has stopped working. I've tried 4 different USB ports on my desktop. I've plugged in other USB devices and the ports are definitely working properly. Any IDEAS????
