I am not sure which software you mean.
I can see your file in a browser, in Acrobat in Preview
It was created in Illustrator and then pdf wouldnt open any information in Corel. Also saved a SVG that did the same thing. They are able to see when opened in browser but when using another software it would try to open and nothing could be seen.
Maybe when you clean up your file with Pathfinder Merge?
And save the file as a PDF version that can be understood in the other software?
It was not due to the way I was creating files. Number of shapes should not affect the ability to open in corel or any other vector based software. It was due to Illustrator Default setting upon saving after updating all my softwares. I only had to change the compatibility setting and that fixed my issue.
