What am I doing wrong here? Whenever I get a change in state (the RC value), I pickle and save to a file (restoreinfo.p). When I restart the application, the serial number is no longer there even though I enter it. Could you please let me know what is going wrong? Thank you.

You may want to use debugging to determine what goes on in detail.

There are commercial debuggers with a graphical user interface
(maybe even free ones). Python comes with a simple command line
debugger ("pdb").
