BIG BIG PROBLEM IN GMAX

ive been workin the past couple of day in gmax and it keeps on having these errors where it tryies to save the scene and then it closes...ill be working on my model and suddenly it'll say gmax has encounted an error and then itll try and save and just shut down...now everytime i open it say ur application has encountered an error no changes were made to the scene gmax will now shut down
wuts wrong i cant open it up without it saying this...but this only happens on the scene tht i wus working on...all my previous scenes i can still work on
