Recently I purchased DXF software and have used it, but every time I go out of designer it doesn't save it and I have to go thru the manage license process to reinstall it. Now it says I have the license but it still comes up in demo mode. I am running designer 1.187 on a Mac 10.9.5. I also have Centerline and conforming Vectors both are ok. Does anyone know how to fix this problem? Thanks
