MBox 3 driver has disabled mic input option?

[MADFERRIT]

Greetings,

I've trawled these forums and as a last resort decided to post for the first time in 15 years!

my setup:-
PRO TOOLS (11.3.1)
Mac Book Pro (OS 10.8.5)
MBox 3 (driver 1.2.1)

Ok…. I've just been mixing a stack of tunes for the last couple of months with no recording done since late last year. Today I went to punch in on a bass track and noticed I couldn't chose the "mic/line 1" mic input as it was greyed out??

Advice on here was to default your I/O.. I did that but the default that came up had no mic input options anymore. I have AVID MBOX chosen on Hardware, playback engine and I/O. Audio plays fine through the MBox and out to my monitors.

When I exit Pro tools and at open the MBox settings icon in System Preferences, the Hardware Inputs are working and I can even plug my bass in and hear it. However as soon as I fire up Pro tools they are greyed out. It seems somethings is disabling them or not recognising them?

I suspect there is a MBox 3 driver issue and have tried both drivers 1.2 and 1.2.1 with no luck. My mic inputs just don't seem to exist. (These are the drivers recommended by Avid for OS 10.8.5). I took a punt with 1.2.2 but this was worse and I had no MBox sound at all…. went back to 1.2.1

Any Ideas?
