Need help

I recorded a meeting for my boss using Pyro software. Once the meeting was over I selected save let it take it's time to finish saving and then closed up the laptop. I just went back to listen to the audio and I have a problem. I can listen to the first minute and a half of the hour long recording and then it stops. My recording length counter (not sure that's the technical name for it) on the right hand side of the screen reads 1 hour and 34 minutes.... why can't I listen to the whole thing. Please tell me it is saved and I can access the rest of that records...
 
Please help :)
