I had FB4 Beta installed and installed the CFBuilder as a plugin (not sure of the "eclipse directory to use" but I guessed: C:\Program Files\Adobe\Flash Builder Beta) and now Gumbo reports that:
An error has occurred. See the log file C:Documents and Settings\ . . . .\.metadata\.log
I looked at the log but unfortunately I am lost . . . thanks in advance
Does changing settings help you? Can you also attach or paste errors from log that can help understand this issue?
