Corel Unable to Save Files

For the past hour or so I have been making no progress because my documents arent saving. Ive repeated some processes more than once and Im just wasting time now. The main culprit I believe is that my computer is saying the CPU is at like 98-100% the entire time this document is open. There is a lot of information with vector splatter graphics, but Ive never had this issue before.

Im using a MAC with Bootcamp Windows 10 and am using SimpleSEPS for a lot of halftone work if any of that could be relevant to my problem. Thanks in advanced!
