If I open DimPro 1.5 64bit as a standalone...the files won't open. If ran in Sonar, they open ok.

I re-read your post and you didn't mention if it was being launched in Sonar or as a stand alone.

C:\Program Files\Cakewalk\Dimension Pro\Multisamples\72 - REX Drum Loops\Drum n Bass Breaks

has (42) rx2 files about 1/2 meg each.
 
Edit- just verified each voice worked. it did. unforuneatly, it crashed the program...twice. Had to re-boot. Got the "Sonar Stopped responding" error. Gray screen.

It would seem we have 2 threads going at the same time not sure if this one has the answer though.

I am also missing these same patch files in new X1 64 install, all default file locations.

          I'm having the same issue regarding in this matter......

I had the same issue.  The default location for Dim Pro is I think in the program files x86 folder, but the expansion packs or others may be in the "regular" program files folder.  Try to copy or create a link to the other. 

I'm having the same issue trying to do a fresh install on a new Macbook Pro....The plugin shows up fine when I launch it in Logic but when trying to load a preset, it says it's missing the wav so it needs to "find" it somehow.....Any ideas on a mac?......moon
