problem with conflict: freespace the great war

[Horst Schlonz]

i've tried the freespace-installer
(http://www.liflg.org/?catid=6&gameid=73). installs fine, runs fine but
at the end of training mission 3 the game crashes with: 

$ ./freespace 
Error: (src/parse/sexp.cpp:4699): Mission name SM1-01.fsm not found in
campaign file for next-mission command 
$ 

next time i run the game i have to repeat training mission 3. anyone
else has this?
