We released a small maintenance release today.
The STEAM Plugin Manager has been updated to our latest version.
It has also been moved from:
"[STEAMLibrary]\common\Cakewalk\STEAM Plugin Manger"
to
"[STEAMLibrary]\common\Cakewalk\Misc\STEAM Plugin Manger"
Both of these fixes were due to changes in Rapture Pro.
