Can't do anything, please help

I recorded a show I was doing as the sound engineer, it's a three and a half hour long show and cannot be re-done.
I plugged an output of the soundboard into my laptop and recorded several tests before the show to make sure all was good, and it was great.
Now that the entire show is recorded, every option is grayed out, even when I select something, I can however push play, record, and the rewind button however nothing happens, I can see that the file was recorded and I can see the waveform.

I tried researching it and came up with nothing, is there anything I can do ?
also, I'm using windows 7 64 bit if that matters, I don't think it should though because I recorded some clips right before the show and everything worked fine

I know this sounds silly, but did you press Stop at the end of the performance? These are the symptoms of Audacity in Pause instead of Stop.
