Trouble with fonts with the 7.3 update

Hi everyone!

Has anyone come up with this issue? CorelDRAW X7.3 uninstalls fonts in windows!!!
I keep on reinstalling them and as soon as I try to open a file with certain 'troublesome' fonts,
CorelDRAW simply uninstalls them and keeps asking to substitute with other fonts!!!

It happens with Opentype fonts.

Thanks!
