Hi, I've been using Parallels v. 12 for about a year and a half now with virtually no problems. However, I just tried opening up Parallels and it freezes and the Mac color pinwheel starts rotating. The only thing I can do is force quit the application. I've tried restarting my computer, uninstalling and reinstalling Parallels, but I still have the same problem. The issue looks like the screen shot I've copied here and Parallels won't start. I need Parallels for my work as a translator and it would be great to fix this rather urgent issue. Thank you
