"This program version cannot load it"

Cubase 7.5 is now saying a project that I started and have only opened in cubase 7.5 is now un-readable. I was just working on it last night, and have opened it hundreds of times.

It says “Project Name was created with Cubase 1.x. This program version cannot load it”.

Why is it doing this? I have opened the project hundreds of times and it was created in cubase 7.5 and has only been used in Cubase 7.5.


This message appears if the project file becomes corrupted somehow.

Solution is to try to open the project on another machine. If it works, you can reserve it there, and try to open back on your original machine.
