Can't open old projects in an updated build?

MeshMagnet

Still learning this engine...

I just downloaded 4.4 and I noticed that my project files from 4.2 are grayed out.

Can I not open old project files in a new build?

You'll need to launch 4.4, then you can try to open than project at which point it will ask if you want to open it as a copy, convert in-place, or skip conversion.

You should convert your old project for 4.4 version for better performance.
