Default Just recharched A/C, now codes 67 and 69

I just had the A/C recharged at a shop. The A/C system had been empty since May 2009 when I had my new engine put in. Before then it worked great. Now I have codes 67 (A/C refrigerant pressure sensor circuit (pressure sensor or A/C clutch circuit problem)) and 69 (A/C clutch circuit) and the compressor will not engage. These codes did not exist before I had my A/C recharged. The mechanics already left for the 3 day weekend so I'm on my own until Tuesday. Does anyone know what could be wrong?

Reset PCM to clear codes. When I started the car, the codes were gone. As soon as I turned on the A/C, code 67 came back and the compressor did not engage.

I took a closer look at the pigtail on the compressor. There are two wires going to the compressor: a black one and a green one. The green one is cut flush with the pigtail. I'm guessing that's my issue? Not sure how that could've happened.
