I could not install on OS X running Lr5. The original case ended with me being given a link which downloaded CC. Not what I wanted. Now I would like a phone # where I can speak to an Adobe representative to resolve the errors from the original case.

You will need to go through the Adobe.com site localised for your location... use the numbers there.
