Trying to open files created on X7 no more than a year ago, and X8 crashes because of missing fonts which actually are not missing.
We also have a font issue (only 11 fonts showing), maybe also leading to X8 not opening X7 files at all. The new font manager is excruciatingly slow as well. Really hope a fix will comes out soon. If even one person in the company can't run X8, we all have to revert to X7.
