Resource manager fail to load 3.0 brush bundle presets. It does not become an active bundle and automatically goes back to inactive . This happened in two different computers, versions 4.0 and 4.1 Another thing I noticed that may help is that if you inspect the resources contained in each bundle they apear different if it is active or not. While on the active side 4.0 bundle appears to have more resource and 3.0 appears to have less.
Update: Somehow, without any action, 3.0 brushes are now active. No Idea how or why that happened. If I can be of assistance please contact me.
Okay, I guess that was just a glitch then. I'll close the bug report.
Not working again.
