A/C Problems again

So my previous thread I had posted about the air blowing warm on the driver side. The freon was low, had it re-charged and it was working fine for 10 months up until now. Now I have no a/c at all. It appears as my compressor is bad. I put my manifold gauges on my low side is reading 80 psi and high side reading 110 psi (ambient temp 75 degrees) and did not notice the pressures changing at all with the car idling and a/c on. So I thought it may be locked our or maybe a pressure switching stopping it? I plugged in my iCarsoft scanner and checked the compressor status and it says ON and it is calling for 100% duty cycle yet no freon is being compressed. So I am just looking for some reassurance here, Do you guys think its my compressor as well?
