Please install v8 Update 2a.
This fixed my VDDK Problems.
I think our Developers added some VDDK Bugfixes or a new Version.
If you still have problems, please open a Veeam Support Ticket. Test Version is as well eligible for support.

Thanks buddy, I'll install U2 and see if it works, then post here the result.
Yes, it was this same version that I just downloaded.
