Was the save location you are trying to load a submerged save? Crash Dive of Doom???
Reload previous save or start patrol again.
Are you trying to use a save file from a previous campaign/version? 'cos you can't.
Did you use SH3Cmdr at all? If so, did you rollback before uninstalling/reinstalling SH3?
So many things.......the last resort will be to remove any SH3 related files from your PC and start again, when I say related I mean anything. Cmdr, SH3Gen, Sh3 Weather, SH3 Save files etc......get rid of the lot so it's like SH3 never existed.
