Error 581 ???

I've recently installed INFORMIX dbaccess Ver: 5.0. When I tried to create a stored procedure I got the message: 581: Error loading message file. It surely looks like an installation problem? But I can't figure out what message file the error is referring to. The procedure is the example "read_address" from the stores5 demos. I've checked the file and directory permissions and they seem to be sufficient. Also, no files seem to be missing according to the table of contents from the installation tapes. (The more "standard" operations, e.g. creating tables, indexes, works ok.) Anybody got any idea ? Thanks in advance.
