Unexpected Return Error! Why is this happening?

[SomeGuys2007]

I just recently purchased a PRS Alpha and I have been NOT using it more than I have been using it. When running a file, It will shut itself off and a window appears telling me "Unexpected return error". Does anyone know why this is happening?
Any help would be greatly appreciated.

It could be a number of things. You want to make sure that you have good USB communication.

In SB3, run the UT command and follow the instructions. Report back with your numbers.

What brand computer are you running? What is plugged into the computer from the machine? Is there a USB hub between the control box cable (which should be less than 12' long) and the computer?
