Files only partially loading - always stop at the same place

[Penguin]

I have the latest version of Scribe. I have two files (from completely different sources). One is 45 mins long and only loads to 41 mins. One is over 8 hours long and only loads to 116:53. No matter how many times i do this, or what format I convert them to (I've tried Mp3 and wma so far) they always load to exactly the same point and no further. They load fine in Windows Media Player and other sound players - in fact everything except Scribe!

 

Any help would be much appreciated. I can do this in another transcription software but I would prefer to use Scribe if possible.
