I have Archicad 23 Solo which I bought a few years ago with the purpose of moving from AutoCAD to Archicad. It didn't happen as I struggled to get to grips with it but I have decided to give it another go. I have enrolled in Graphisoft Learn as they have what looks like a few good tutorials. The problem I have encountered straight away is that the course files will not open in my 23. I am guessing this is because they are version 25 files. Can these files be saved to version 23 any way, or is my only option of opening them/completing the course by purchasing Archicad 25? The files for the course are .pla
