Imported Coreldraw CDR files in CorelCAD 2017 are blank?

Hello, for some reason when I use the Import Coreldraw option in my CorelCAD 2017 to bring in a CDR file, it processes for a second, then nothing ever shows up. I've tried existing CDR files, and then some basic ones I made as a test, just a box. Nothing ever gets into my CoreCAD. Any ideas what could cause this? Thank you.
