Knowing all about your source files, plus that other info, will allow someone to help you quickly.
The source files are mxf files, and they are all stored on a Lacie 4TB drive. This has happend before so I Un-installed and re-installed PP CS6 and opened the program. Once I linked one file everything became linked. Now, it only lets me link the media 1 by 1, this is a large project, and with some files it gives me a "There is a Generic Error". I am working on an IMac the lastes version OS.
I hope this helps.
Sorry Raphi, I don't understand: Are you saying that linking one-by-one, the files are successfully re-linked? Or do those also get the generic error? I'm with Jim; sounds like a missing codec issue...
Care to post one of the files (a small one), somewhere we can try importing it?
