Gui. editor hangs when trying to save the project. The attempt to open a project fails. I get the message "argument out of range". Given that worked on this project for a few weeks, I have a big problem ... Until yesterday, saving configuration was no problem. Today I made a few small changes (2 group addresses to assign ) I am not able to open my project. Uninstall and installation given nothing, run with administrator rights too. Any ideas?
