Hi, Aeroglass was running, licenced, on this new Win 10 64 bit laptop- no watermark. Suddenly the watermark appeared, and the machine code is different. I have just installed Hyper-V, and tried to create a Win 8 virtual machine. I'm entitled to 3 codes, but all are issued. There is a 30 day period... and I've done nothing that should have invalidated this. Any thoughts? Thanks!
