Saved game crashes

Hi, as a lot of people my game is often crashing. Usually i just launch back the game but now I can’t load my save anymore. When I continue with my current character, just at the end of the load screen the game immediately crashes. When i try another mode (with matchmaking) I can just see my weapon & then the game crashes. It seems that it is corrupted or something. Is there any fix or help ? I don’t want to lost my lvl 17 character… Is there any way to send a ticket to gearbox directly or just the forum? Thanks.
