Imported audio gets cut off

I've seen many things on this forum that resemble my issue, but not exactly....  I am using Presenter 09 and Powerpoint 2007. 

I have a 51mb audio wav file that I created in Studio One.  I've imported it on slide 1 and then went in to the audio editor to spread it across the slides properly.  The audio file is supposed to cover from slide 1-34.  It stopped at slide 10.  The audio was cut off. 

I have a second file that was for my slides 35-66 and it did the same thing but that one ran for 20 slides before it stopped.  Any ideas?  Is there a import file size cap that I don't know about?  Thank you for your help everyone.  I really love doing this stuff!
