CAHeadless has encountered an error.

I have just installed adobe photoshop elements 12 & adobe premiere elements 12 on my Mac. After doing this I have various error messages popping up with this title "CAHeadless has encountered an error." two of which are "[/Adobe/premiere/elements/main/MediaCore/ASL/Foundation/Make/Mac/../../Src/DirectoryRegistry.cpp-283]" and "[/Adobe/premiere/elements/main/CAHeadless/Make/Mac/../../Src/CAHeadless.cpp-683]". I do not understand either error message or know the process to rectify the problem.
