Why Does Corel Say Installed Fonts Are Missing When I Open Previously Made CDR Files.

So I've had a lot of PC/ Corel Issues Today but I finally managed to get one thing done. But now when I open files it says fonts are missing and to substitute them with other fonts. This happens occasionally and I can usually just select the same font that it says is missing, but in this case Corel cannot see the fonts I've installed. So I tried reinstalling multiple different fonts and it doesn't fix the issue. 

Whats going on here and how can I fix this? Do I just need to repair Corel? Maybe reinstall it? Maybe its an issue on the PC end? I don't really have time right now to do all that So I'm gonna just convert the text to curves on another devices for now and work with that until I have more time to fix this.
