The problem is with rateup being unable to update the log files and create the graphs.

Check the permissions on the files and directories: the process running MRTG should be able to write to the c:\mrtg-2.16.2\MRTGData\Router directory and all the files within it.

My guess is that there is a permissions issue meaning that it cannot open either the .log file or the .png images for writing, resulting in a bad file descriptor (although surely rateup should check for success on file open, if Tobi wrote it well :) )
