Its a known issue in X1 heres the fix...

Thanks for the suggestion, but this issue turns out to have nothing to do with memory allocation, process parameters, registry issues, etc.  It looks like a corrupt plugin.
 
When I select a different Dim Pro plugin, I can playback the project and export audio without error.  The hangs and crashes occur only when I select the Warm Strings Pad 05 plugin.
 
Cakewalk has been sent a couple of core dumps and I will contact them tomorrow to get advice on the best way to reinstall that one plugin.  I assume that I'll have to reinstall the whole library, which could potentially screw up modifications I've made to other Dim Pro plugins referenced in my other projects.  In other words, I don't know whether Dim Pro plugin tweaks get stored in the .cwp project files, or within a Dim Pro library folder that could get nuked if I reinstall it.  If anyone can clarify, that would be greatly appreciated.
 
 

The "Warm String Pad 05" is a pretty simple patch. Two flac files and a few DimPro tweaks stored in the program file. If something is messed up with the patch, it might be indicative of a bad installation. The patch plays fine here in standalone mode and in X2. Have you tried playing it in standalone mode?

I am not sure what you mean by modifications and tweaks to DimPro. If you have altered the settings of DimPro in a project, the project maintains that information. If you have altered the settings in DimPro and saved the settings using the "Save Program" function within DimPro using the icon immediately to the right of the program window, that is different. Those changes will be lost with a reinstall.

I tried playing Dim Pro "Warm String Pad 05" stand-alone, with VST Host, and it hangs that program just like it hangs SONAR.   This would seem to confirm that there is something wrong with that particular plugin.  That one is perfect for my project, tho.

By "mods and tweaks" I meant changes to settings within a project, so it sounds like I wouldn't lose anything in a reinstall.
 
My main concern regarding Dim Pro reinstallation is that I've added several supplemental Dim Pro libraries like Digital Sound Factory Classic Keys & Vocal Expressions, Expansion Packs 1 and 2, etc.  Do I have to reinstall all of these if I reinstall the base Dim Pro software?  It looks like the installation program is '04_Dimension_Pro_1_5_Setup.exe'.
 
I can't get through to Cakewalk Support so any guidance is appreciated.

Backup the folder where are the samples are. Put them back if missing afterwards.

It is not as simple as backing up and restoring the samples. Even if it were, since there may be issues with the original installation, you might be restoring bogus information.

If you do not wish to contact tech support, which you should do in this case, the best alternative is to perform a clean install then reinstall the expansion packs and DSF libraries. Here are the instructions for performing a clean install http://www.cakewalk.com/S...eader.aspx/2007013238. The 04_Dimension_Pro_1_5_Setup.exe is the correct installer.

It should be as long as you delete programs.lst (to reindex) after you've copied back the samples .
Now if the samples themselves are corrupt that is another thing...
