I have a functional copy of RealChat version 2.1.2 and would like to upgrade to version 2.2.2x. The registration code is somehow embedded into the .class files and is impairing the upgrade. It looks like the upgrade refers to replacing the .class files. There is a file called reginfo that is supposed to have the registration key that tells the .class files what version to load. I have the file, however, it is empty. Maybe someone here can repair the files allowing for the upgrade or perform the upgrade for me.
