Can't burn a blu-ray disc

[tacua]

The last few times I have tried to burn a disc with your software on my external Asus BW-16D1X-U I encounter this error.  The error box comes up, I filled it out but it won't send.  Ashampoo has no problem with the files, which are for backup of my photo files, CR2 and xmp.  It's a drag as I prefer your software's interface over Ashampoos, but it does not seem to work anymore on my computer.  Here is the error file that I could not send:

A fix for this will be available with the next version.
