Crashes when loading

[Paranyxidas]

Hi everyone,
I'm playing sh3+gwx+commander for two years and finally I need your help for first time...
im in the middle of a patrol and when im trying to load my saves I get an error message when the I read on the screen "not so long ago".
Also I noticed that ships are sinking without to attack them when im close to a convoy.
This happens for first time so I don't think is a pc problem.im in patrol 24,November 1943.
Do you think the problem is that I loaded the game from sh3 icon and not from commander?the problem started when the next time I loaded it as usually from sh commander.if yes,the solution should be to start the patrol again?

Thank you...
