Bootcamp Win10 not working in PD 12.2.1

Hi,

I know High Sierra is Beta, but we are now on Beta version 3, and most other developers have gotten their applications to work with the new macOS. Not Parallels...

A Bootcamp installation of Windows 10 have worked fine for months now, accessing it via PD (I have imported the Bootcamp), but since the upgrade to High Sierra, I get a bunch of errors when pI try to start it from within macOS. It starts up all nice, but soon I get the "The specified file cannot be used as a virtual hard disk"... followed by "Unable to connect Hard Disk 0"...

I know it says this is a know error, and that they are working on this, but come on now...
