First of all. Superb job on the patch Phil (& team). I am seeing much better performance now, and actually enjoyed FSX finally.However, I do need some guidance. I pulled these out of the Application logs."Product: Microsoft Flight Simulator X -- Configuration completed successfully." - 17/05/2007 9:44:11 PM - YAY."The hardware has changed." - 17/05/2007 9:45:15 PM - huh?"Product: Microsoft Flight Simulator X - Update 'Microsoft Flight Simulator X Service Pack 1' installed successfully." - 17/05/2007 9:49:11 PM - YAY!"Acquisition of End User License failed. hr=0xC004C008Sku Id=30fab9cc-8614-4339-989f-7ce61fb7a5c4" - HUH?!?!Yes, Vista lost its activation. I have three days. I would like to know what the best course of action would be... because I am NOT reactivating Vista and using up one of three precious activations when nothing was changed hardware-wise.Yes, this is my operating system... not FSX license. In three days, my computer becomes a brick and I've done nothing but install your software.Again, SP1 rocks... well... for the next 2.5 days anyways... and I'm working all weekend :(

Goodie. Problem solved. Thanks for the help, you know who you are.MS Support wanted my logs, or to remote in so they could see what was going on. Told them that they managed somehow to determine that my hardware had changed without either remoting in or viewing my logs.... so they can fix it without it as well. I mentioned the things you told me about, and they quickly released my product key :)Again, thanks.
