The Lighting Controller

Just did the upgrade to v8. Can someone help me out with this error? It sees my fixtures when I create a new scene just fine, but these "old scenes" aren't working for some reason and I am hoping I am not going to have to rebuild them.

It does this then shuts down on my Macbook pro.

Thanks!

It looks that, for an unknown reason, the fixture "RGBAW 9 Channel" has been deleted from the folder "../YourLightshow/fixtures/".
V8, which is "fixtures based", needs this fixture.
