Adobe Send does not complete upload

I have made multiple attempts to upload and send a file.  All have failed.

I am trying to send a 5.7 Gig mp4 file. 

I have tried to do so on both a OSX and a Win7Pro 64 bit system both with different internet connections.  Both give a file failed to upload when the file is 80% done.  Interestingly I tried a 8.4 Gig version and had the same issue at about 90% uploaded so It does not seem to be the file size.

I got this service specifically for this purpose.

Sendme Now tells me the file is too large.

Any assistance would be appreciated.
