Dear Mansoureh,
Floating Point Exception is a very generic error, check it on wikipedia 
(if it accessible from Teheran). We cannot say what causes it from the 
little information you provided : it could be a bug, a compilation 
problem or even an mistake in your input.

Why don't you try the latest version 5.0.3 of the code?

best regards
