Exporting XML to AAF

We have seen this error previously, but need to get your media in order to resolve it.
Would you be able to supply us with the file named "Untitled1"?
I am not sure if that is the file you said was 13 GB or not,.

I can supply an FTP location for you to upload the file, or if you want to put it on a USB drive and ship it to me, i can offload the file and ship it back to you.

Please let me know how you would like to proceed.

I get this error message.
I have cut down my time line into chunks and exported those to identify the problematic file.
For this specific error message I found the file in question. It is a quicktime file. It is 13GB.
There are other files like this that seem to trip up the exporting process, all of them are quicktime.

any suggestions?

Thank you.
