GSE stoped working

Today i helped a friend set up his GSE. after we where done i wanted to edit one of my macros. The GSE would not let the macro be changed. Saves would not save the changes. I try to make a new macro would not save changes. The only thing i was able to do was to delete a macro. I’m using 2.5.11 . My friend has the version and we got him up and running with no issues. any ideas
