Thanks brundlefly
No, I have not applied the "e" update. I didn't know there was one. I'll have to look into that.
In addition to the update I may have found the source of the problem:
I bought a new DAW before installing X3. It has 4 hard drives.
C: To be used for programs
D: To be used for projects
E: To be used for samples
F: To be used specifically for East West Quantum Leap samples because it's a huge library.
Upon installation of Sonar X3 I selected to install the Cakewalk Content on drive
E because that's where I wanted all the samples to be stored. I can now see that Track templates, Project templates etc. are also stored in that Content folder. Even though I mapped the paths in Sonar's file locations to the correct drive and folder I think that having those files on a separate hard drive may be causing problems. So I think I'm going to relocate those folders and then re-map them in Sonar's file location preferences. I'll give it a shot and see what happens.
