Hi Thomas,
That probelm sounds exactly like mine. However, I powered of the vm, set the ctk option to false in the advanced Options, removed all snapshots, turned the ctk Option back on, power on and off the vm, created a snapshot and deleted it. Then I tried again and I still get the same error.
I just tried to clone the vm with vsphere Center. Using the resulting vm, I get the same error.
Any ideas? Did I do something from while following your fix?
Thx
