I know this is an old topic, but I thought I'd add here that I had this exact same problem and the issue was that SlickEdit did not have write permission to the directory where the *.e script files were stored, so it couldn't write the compiled script file (the previous build probably had the same problem, but since the scripts had been, at some point, written by the SlickEdit compiler, it didn't complain until I upgraded). The error of showing "out of date" isn't very helpful in this situation.
