No sound when recording in Logic Pro X

Hi,

I can hear no monitor sound when recording in Logic Pro X. I can listen to all other tracks, but the track which is set to record has no sound (just when recording).

I'm frustrated cause I lost a guitar session (Amplitube's distortion was essential for monitoring the guitar sound), so we decided to record it another day.

I tried managing the basic stuff like:

- clicking/unclicking on "I" button...

- changing the channel output (Buses, outputs...)

- enabling/disabling "Auto Input Monitoring"

- enabling/disabling "Low Latency Mode"

Any ideas?

I am using an interface Pro Fire 610, and Mac OS X Mavericks 10.9.2. I had no trouble like this when using Logic Pro 9 before.

Hope someone can help me,

Thanks
