UHD CREATOR not creating burned disc or ISO file

[C.C. 95]

Curious....
So I have a UHD file of a film I want to burn to a BD50. I selected conversion and fit to disc.
It starts- and ends at 100% and then....nothing. No opening of IMGBURN to burn the disc.
Then, I decided to I'd try to just make the ISO and then go to IMGBURN myself with the ISO.....same thing. (It left me with a 5KB .MDS file).


I then truncated the uhd file down to 1 minute long for testing purposes - and that chunk was converted and burned!

So why does the full movie file not convert and burn or successfully create an .ISO file?!

Please name the file that you wanted to convert and provide the dvdfab_internal log file as well as the burnlog file to us, thanks.
