This does not work for me.
I have a very simple PPro CS6 project file. I opened it in PPro CC, which then converts it and saves it as a PPro CC project file with a different filename.
In Adobe Encore CS6, I go to File, Adobe Dynamic Link - Import Premiere Pro Sequence. If I select the PPro CS6 file, it works like it should.
When I select the PPro CC file, it claims it's loading the file...but it hangs.
I'm on Win8 Pro x64 with both CS6 and CC suites installed.
