** Error requiring custom function file 'C:\... **
Other people have reported the same (or similar) errors and all/most seem to be on Windows servers. I'm afraid I don't know the cause so I can't say how to correct it.
You can try searching the forums to see if any answers where posted about any other plug-ins which malfunctioned that way. At least one case I remember was that the calendar.pl file itself was corrupt and downloading a fresh copy and reuploading in ascii mode solved the problem.
