thx for the response, this project is runing on a Q12H CPU. about the licence, my colleagues are telling me it's a full licence. personal I'm totally new in Mitsubishi. how does it work to update GX developer? I FOUND THE CAUSE!!: "Suspended because unmatched No. of items exceeds 100." a little detail to the project. somehow we lost all comments between the networks (all device comments are still present). So in a verify we get a lot of mismatching items. does anyone know if this is an setting or fixed limit?
