Problem with exporting files from corel x7 to cut & command all of a sudden

Have been using Corel x7 for the last 2 years with my Tracker CNC and Cut N Command software.  Never had any issues until just recently.

Files are export to PLT (HGPLT) format and then opened in cut n command.

Just recently after a large job, my files won't pull in without creating some weird problems with the cnc side. Things like the torch descending when lit instead of piercing and moving on or making the initial pierce and 1st cut but then moving to the next cut location and not descending to material etc.

I have ruled out the cut n command software as a problem or the table settings itself. If you draw directly in cut n command it works perfectly.

I have a ton of jobs to run and am dead in the water.

Can anybody help?
