CocoStudio 2.3.3 Cannot open file

I’ve upgrade from 2.2.x to 2.3.3 and get the error when opening file ( layer, scene … ) while it was ok in ver 2.2.x
It shows me “opengl missing gl version”
How to fix it ? Or I have to get back the pre-version ?

I have same problem with win7 SP1 x 64. If I return to version 2.3.2.3 don’t have this problem, but can not open file because it was open to new version
.

I also have the same.

In fact, I have never used CocoStudio in a Windows PC. Does it really work on Windows?
