Audio Folders Missing

I’m running Cubase 7.0 on an iMac 12 GB ram, intel core i5.

Over night, two days after I installed Yosemite and ran Cubase 7, all the audio folders for all my projects that go back to day one disappeared.

When I search for them, they appear with no contents. In the project folder the audio folders do not appear within Cubase. I follow the paths described in the missing folders screen.

I looked for the files as specified, they don’t exist even in the time maching but the cache and .cpr’s do.

I reinstalled Cubase 7.0 with the installer for Yosemite.

I’ve never seen this behavior and I am very concerned.
