Logic Pro X crashes whenever I try to share files to iTunes

Hi guys,

I've been putting mixtapes together on Logic for a mate's 21st next weekend, and whenever I try to export any of them, regardless of the length (usually about 45 minutes - 1hr, but I tried with a 3 minute file and that didn't work either), Logic gets right to the very end of the process, having converted it to AAC, then crashes.

I'm running a MacBook Pro i7 2.5GHz, with 16GB DDR3 RAM and plenty of space on the Hard Drive on OS 10.10.4, so I can't imagine that it'd be crashing for want of more computing power.

I tried exporting in lower quality, which also didn't work, and also to Soundcloud rather than iTunes, all of which had the same effect. If anyone could help me on this one, it'd be very kind!

The crash data is here for those of you that understand such things, I've not a bloody clue how to interpret it
