I bought a Monster iStudioLink instrument cable today. All I had to do was plug it into my laptop, start GB2 and pick my instrument and record. Unfortunately, it is not recording. My line in is not muted. Under system prefs I see the bar moving as I play, but nothing is recorded in GB2. I did everything that their help file said, but no joy. Does anyone have any ideas? I should say that the plug does not appear to fit in all the way, but i checked it with my mic and it works fine so I am completely unsure. Thanks!
