Did you move from a setup with two monitors to one monitor? Sometimes we see this, and Windows remembers the last position of the window. The position is saved in the Registry, and is likely off your screen. The only solution is to use REGEDIT, navigate down to "c2config" and delete that key.

What exact version of CAESAR II are you using? I'll give you the exact key (path) to delete.

You can't change "Code years". A specific version of CAESAR II supports a specific edition of the piping Codes.
