Mimaki Fine Cut plug-in with Corel 2018

I don't think I did my research enough. I upgraded an old computer running X4 and X7 with Windows 7 and an original Fine Cut 7 plug-in for a Mimaki CG60SR Cutting Plotter to a Windows 10 and Corel 2018 and now unable to drive the Mimaki. Fortunately the old computer will still do the job (for the time being). I can't even find where to download Fine Cut 8 as they all seem to be upgrade versions then I have the ability to install X7 on the new computer and that should work?  Any other suggestions??
