It seems that MMM2014 will not recognize my microphone when plugged into my PC. It worked perfectly for a couple times and then stopped. I plug in and set the REC functions but the level meter indicates no input and flashes inconsistently  when I hover the mouse over it... strange. The Mic port functions just fine in Magix Studio 2 so I'm certain it isn't a problem with the PC port nor the microphone. Any ideas? THANK YOU...
