I purchased a line 6 studio gx at the beginning of last year (2011) and was able to use pod farm 2 with no problem at all. After having the device stowed away for about 5 months after its last use, I recently tried hooking it back up to my macbook and noticed a few things didn't work.

      First off, the output is working however it's only on clean, no preset sounds work (presets that do not require purchase). I also noticed the tuner doesn't work either, I assume because the "In" gauge in the upper left hand corner barely registers anything at all. After installing all current updates on Monkey I had the same problems. I thought that maybe this was all just a problem with the usb input settings on my computer. I went into system preferences, then sound, and set my input to GX and output to built-in, tried switching USB ports and cables (both USB and guitar) and still nothing had changed.

     Still confused, I tried a few google searches and read a few similar cases on this forum. I tried uninstalling and reinstalling drivers, Monkey, Pod farm and Pod farm 2, and License Manager, I deauthorized and reauthorized my GX and computer, and still nothing had changed. I also went to the mixer and noticed neither tone A or B were able to be activated. At that point I was unable to find any new material that could help me in any way.

Does anyone have any suggestions as to what could be causing this problem? I have a feeling it could be an easy fix I just don't know exactly what I'm doing.

My current operating system is Mac OS X 10.6.8. Thanks!
