On a PC running Windows Vista, I installed version 1.18 of KaraFun and created 250 working files. Then I bought a PC with Windows 7 and installed the latest version of KaraFun, but on this PC, the files I had created with the first PC did not open and also the KaraFun Editor wasn't available. I then installed the old version 1.01b, so I got the editor, but this version does not open the files previously created with version 1.18. Is there an automatic way to open files with the extension KFN with KaraFun 1.01b on Windows 7 that I had created with KaraFun 1.18 on Windows Vista?
