Dear Stefano-if you are using the CDU drivers for the 737NG, you need to make sure that:a) You have purchased the 737NG 800/900 - this doesn't work with the older version (but if you have the 800/900, it works with the 600/700 later):( You have selected the 737NG when installing the CDU drivers. This will update some important files so that you don't experience this crash.c) You have updated the CDU firmware to v1.03, as instructed in the readme files.For further help, don't hesitate to email our support.Thanks,
