error during the rescue in prenit versions

[Jokerinoprogrammer]

Good evening.

I am having an issue with autocad 2013 , every time I save a file in a previous version of the program I get this error
unhandled c015000fh exception at 779df7bah, and allows me to save only in autocad2013 version.

What does it depend on?

Thank you.

try to save without changing the version, but setting the save format via "options\open and save"
