Software to cut from X3 using Creation cutter

Hi All,

First post and would appreciate some advice.  I use X3 and until recently have used Flexi 8.5V2 to cut vinyl on my PCut Creation 630 plotter.  Every few months I would have to delete the software and reinstall to clear up issues such as several passes on a cut job or the plotter cutting a job 2-3 times the instructed size.  This week however, reinstalling the software is not making any difference.  Can someone please recommend a program that will work easily and is not too complicated to operate or install, I'm not too tech-savvy.  Will most programs work with any cutter?  Is there a program that works well direct from Corel?

Thanks, Steve.
