There is a new maintenance release of FDS/SMV on
http://code.google.com/p/fds-smv/downloads/list
Please note that for those of you who are not using the 32 bit Windows versions of FDS, there might have been a change to the name of the executable. After downloading the new version, go to the directory where the program was installed and check that there are no older versions present (or rename them if you want to keep them). When in doubt, simply type the name of the executable at the command line and see that the release number is the most current.
