Hello,
 
Installed and all seemed well. I went to use and the first four or five (most were the 12 string) would cause DP/Sonar to hang.. I am able to exit out but if I try to do anything with the instrument, I get the white screen. I then also have to use task manager to kill the SonarPlt process. I also was able to replicate in a new project where nothing was added except DP. All the other patches work fine in DP... Can anyone else confirm...?? Thanks

The way it has been installed it appears non standard, so I'm not surprised , check "Cambridge is here." thread.
 
However I tried running Sonar as administrator and not running Sonar as administrator and it all worked.

Update:
 
Seems to be related to my "recording" buffer setting.  If I move my buffer up from 48 samples (I tried 256 and 512), the trouble samples do not give me any issue. If I go back down to 48.  The issue returns.. I will consider this an adequate workaround for now. Thanks

Confirmed.  I have the same issue on my system.

Yeah I have this same problem.  Some of the patches in Les Paul Gold Top Expansion Pack cause Dimension to crash no matter how high I set my ASIO buffer settings. 
 
My test case wasn't very difficult.  Blank project, add Dimension(audio+midi as separate tracks), drag in a short MIDI clip (some 4-bar rhythm guitar loop, I'm not sure where I got it).  With my normal ASIO settings Sonar/Dimension would crash about half-way through playing the loop using the 12 String Bright patch.  Upping my Focusrite Saffire (first gen) ASIO buffer to 20ms (from 16ms) would let the loop play.  But adding a second copy of Dimension with the Bass 8-String and another copy of the short MIDI Loop (transposed down an octave) would take Sonar down even if I increased the ASIO Buffer Size to 40ms (the highest it will go) this is at 48khz.  I sent one of the fault reports onto Cakewalk.

Yeah, I got the WSOD jumping around between patches too. It went away after restarting Sonar.
One possible workaround: Load DP, Load one of the Les Pauls, save the project, exit Sonar.
After that things will probably work normally.
I haven't had a lot of luck tracking this kind of problem down, no one ever seems to be able to reproduce it, odds are you've got something installed on your machine that Sonar doesn't like and you'll probably never find it.
That being said, Cakewalk is not the only vendor that has this kind of problem, getting Cubase to work was a complete nighmare. In both cases I suspect the issue has nothing to do with the user level applications and everything to do with the operating system environment.

I have trouble with the Neck Power Chords patch. It works fine at 44.1/16, but it hangs after a couple of chords at 24/48 and causes Platinum to shut down.

FWIW, I auditioned all of the patches yesterday with no issues (24/48 with 256 buffer)

They all auditioned fine for me, but when fed some number of chords/long sequence would blow up.  The crashes occurred in Dimension itself, which makes me think it's a bug in the instrument.  Even if the ASIO buffer isn't big enough, software should never crash or lock up.

Oh I see...yeah I was just auditioning with a controller.
