An-225 0 Posted July 15, 2010 (edited) I just bought and installed the boxed version of OA (automatically merged with A2 and now I have Combined Ops). I selected to install it with the option of using the DVD in the disc tray every start up (rather than activating it online), and the first time I tried running it, it worked perfectly. But on every subsequent attempt to run OA, it closes the application back down with the error message: "Bad serial number given in setup." Any help is appreciated.
