Error Timed out waiting for XPC response

JC,

I hope you are doing well and your new year is starting out nicely.
I wanted to see if you had been able to install the 3.0.6 BETA software and test it with your FCPXML.

Please let us know how you are getting along and many thanks.

Dear JC,

Will forward you a link to upload the XML to.

I keep getting errors similar to the one below. I'm trying to export a 55 minute show. Running Yosemite 10.10.5, FCPX 10.2.2 and just downloaded X2PRO today and using for the first time. XML is 8mb so can't upload here.

An error occurred converting Final Cut XML to AAF
