Simple work Around to bundle problem
I wasn't able to save previous projects in the .bun (bundle) format in Sonar 7 on my PC. I wanted to bundle them to transport them to my laptop. I went to the Cakewalk projects folder on the PC and copied the project folder ( i.e... C drive -> cakewalk projects ->" my song" folder) to a thumb drive. The song folder includes an audio folder and a project file. I imported the "my song" folder to the Cakewalk projects folder on my laptop and it opened fine sans a few plugs that were missing because they aren't installed on my laptop. Simple solution.
