Mbox 3: Input 1 stopped working

[vocaleyes]

While using two mics to record through my Mbox 3 input 1 stopped working completely. I've checked all the inputs and switches and they are as they should be. I reinstalled drivers, rebooted my PC, and tried different instruments and still have no signal. Input 2 works fine. Everything else seems to be working correctly. It seems to have come to the point when I need to take it to a service center for repair. I have an M-Audio Fast Track but am unable to get PT Express to recognize the hardware. If I could use the fast track while mbox 3 was being repaired I'd at least be able to continue working. Do any of you guys know a way to solve this issue with the Mbox 3 or is repair the best option? And is there a way to use my old fast track with PT Express? Thanks for any help anyone might be able to provide.
