Hi,
I had issues w/ additional content not showing in Dimension after installing some additional DSF libraries recently. I finally figured how to fix it and maybe it'd help.
Locate the
Dimension Pro Content Folder (typically, this would be installed as: Macintosh HD > Library > Audio > Plug-ins.
In that folder, there should be a sub-folder named
Programs in which you should see a file named
programs.lst (last file in the screen capture below)
.
Delete that file. It will force Dimension to re-scan the content and your library should (hopefully) show up.
