well weird thing is that an xp computer did it the other day, now the guy it happened to is not a computer guy by any stretch LOL
Only way i can get that to happen here is if i select the wrong com port, meaning my actual com port for the cable is COM 5, which can be verified in device manager, unplug and plug device in and should see the com port show up or go away. Anyhow in my drop down menu i also have a com 3 that is always there, though its not my flasher, if i select it, it will disappear once i hit connect and tell me to set my com port. Any chance you are doing something like that?
Give 2.1 a whirl, then let me know if you have more than 1 option in your drop down menu for com port selection etc.
Sorry for the hassle, we will get it though, this is a brand new one surprisingly there are a lot of these things out there reading gauge data LOL.
