I had to come back to this topic having read it then having problems with the LTR version of VinlyMaster..
I was trying to Vectorize my CorelDraw files. VM does not recognize CDR files so I exported as AI files.
When imported into VM they had vertical lines in them. I exported as JPG and after vectorizing and sending
to the cutter I would get an error message of "nothing to cut". I exported in quite a few formats and always
the same message. I even took the images and put them in programs like Inkscape and Paint and re-exported them
trying to strip whatever VM didn't like about them.
Only when I exported my corel files as "Tif's", did they vectorize and cut correctly out of VM.
I don't know if any of your problems correlate with mine but just wanted to post maybe helping someone else..
Oh, I'm using Windows 8 also but don't feel that Win 8 had anything to do with my problems..
