I have a problem, when i turn on my Presonus Firestudio project the lamp turns red and after a couple of seconds it turns blue and is good to go. Suddenly when i was in a recording session last night it just turned off. I've tried pulling out the cables and plug in again, turn on, off several times as well as plug out and in in the PC but nothing works. It turns red, then blue and the different track/plugin lamps blink and then the power button turns red again. It's like it's not turned on. My PC finds the device offline and i can't record anything, but if i plug my headphones to the device i can hear the instrument, but it wont work with the pc. What do i do?
