Compressor 4 can't export AIFF file

Hi all!

So yesterday i updated the OS to Maverick. Suddently i couldent open Compressor. I had a video due for yesterday, so i deleted the compressor, and bought the ned compressor 4 from app store. I had to make an AIFF audio file, for use in a FCPX video. I use these things as a professional, and i therefore have to find some kind of solution, and that FAST!

When i try to compress a MP3 file or any kind of format to the AIFF format in 48000 sample rate, compressor makes a track with a bunch of holes in it.

A sample track in the fully working m4a format can be found here:

And a compression of the same file into a aiff format with a sample rate of 48000:

PLEASE SOMEONE HELP!! I SERIOUSLY NEED A SOLUTION FAST!!
