project rollback How to rollback a project version?

[Helitop 0]

At first I worked on 1.2.9, but then I changed the version. I started working on the new version of Mine Imator 2.0 Pre Release 5, but it takes too long to render the animation. I decided to go back to 1.2.9, but I get an error saying that I need to update Mine-Imator. I don't want to redo the whole project, what can I do?

I think you are stuck with the new version now. This is why im going to wait until they polish it.
