Goodnight folks, im a brazilian guy so sorry for my english.

I've afcad 221 and it is not oppening cause when it starts and begining compiling the airports it gets error signature "unknown" and a message appears saying it need to be closed.

Do you know something about this??? Could you help me???

Thx

have you tried to reinstall the program?  it sounds like either there is a file missing that should have been installed, or in some way you pointed to a folder that your FS9 is not in.

try reinstalling AFCAD 221 and see if that helps first.
