I have only used my x-aviation library of 4 aircraft on this machine. But, during the next license check, it is reported as Machine ID invalid. I put my username and password in and it brings up a box listing 3 ID's. All of them are older than the next and all refer to the same computer. I don't want to make the mistake of freezing, so, what should I do.
Any help is appreciated and how to remedy.
