Hi, I am having an issue why my Digilent Analog Discovery 2. Whenever I try to run my device, I get an error message saying "PPL not lock". I would like to mention a few details about this situation. Firstly, this is the first time I used my Analog Discovery 2, so it is brand new and has not been touched before. Second, I switched the usb ports, tried connecting it with a different computer, and tried using an external usb port. All of which resulted in the same error message. Finally, I want to say that it was working earlier that day. With all this being, I would like to know how I could get this fixed or if I could get a replacement for it. In addition, I was using this device for a class assignment. Hopefully, this information can be useful to fixing my issues. Much Thanks, Kimson Lam
