A friend gave me an offical usb stick with unRAID Pro2.key (one of the two pairs key by $149) ten years ago. it was unRAID 5.0. For some reason I didn't use this usb flash for couple of years. I never transfer this key to other usb flash stick. Today when I updated my unRAID server from 5.0 to 6.11,unRAID 6.11 told me this:
How can I get my Pro2.key back?
thanks.
This is my SanDisk flash disk. its instance id got by Hwinfo:
DeviceInstanceId : USB\VID_0781&PID_5591\0501C4D9E6EF744F8116A7743D6BA89770C72E617ABBB393C2C2C15C33AA3F839E92000000000000000000002544E30B0016041091558107A62B38D4
And its GUID from unRAID is : 0781-5591-9155-8107A62B38D4
Got it?
