I did a couple of google searches but couldn't find anything on this.  I ran a fully clean install of X2 recently, but noticed that DimPro appears to be missing a fair chunk of sample files (most notably pretty much everything in the 'Vintage Synth' folders)as well as various other sporadic sfz nulls.  I twice tried a re-install of just DP but don't seem to have any luck.  The additional strings set installs ok, and the synth is playing fine in other respects.
 
Anyone else seeing this, or have any ideas?  I have the same issue with both 32 and 64 bit installs (and assume they are both referencing the same patch sample set).

Could be the DimPro stuff that came on the SONAR 8.5 additional content disk needs to be reinstalled.

Yep - this caught me out last week when I was reinstalling

Ah I wonder whether that's it then.  The old additional content folders are still there but not the samples.  I'll break out the 8.5 disks and see what I can do.

Cheers guys - much appreciated.
