hello:

i have a problem with this great game. i was playing it and when i stopped i made a savegame. but today i enter in the game, and load the savegame. but i can´t do anything because the moment i click to intecract with the game it crashes to desktop. the game is not freezed because the animations are running. i tried to start the game again and there is no problem. maybe my savegame is corrupted?

It could be corrupted. Try an older savegame and see if it also crashes and also try your current savegame again, maybe it was just a temporary glitch.
