Well, I think there must be something wrong in my system (fresh windows install 5 days ago).

I opened Solo, added a drummer (EZDrummer Core library), then changed the snare, loaded a mixer preset and saved it. Closed Solo, reopen solo, tried to load the recently saved project and I get the same error.

The projects saved in 1.0 are opening, but If I save again in 1.1 then the project gets corrupted.

Can anyone confirm this issue?
