I made the mistake up upgrading DP before I had researched. I love Dimension LE. But it has become a casualty. I updated it to the latest version but it still comes up as missing. I'm not certain the version I had before was 1.2. Maybe that's the problem. I can pull it up in standalone. I'm on a Mac Pro (intel) 2.8ghz, 10.10.5. DP 9.
 
I'm sure this is my first post to the forum.  

Rapture Pro can load your Dimension LE presets.  I'd try the demo first to make sure it runs well in your DAW.
