URGENT - "Generation Error" in order creation and modification

Hi friends!!

We have a very strange error, when modifing or creating an order (IW31 / IW32) the error "Generation Error" appears, when debugging it doesn't appear any message call, or rise exception... it happens all the sudden when a module is finishing (in diferent places for IW31 and IW32).. In IW31 after trying to complile the message appears...

Does anyone has had a problem like this???

Please Help!!!

Thanks is advance!!
