Navigraph CTD and slow graphic

The last five weeks I have had issues with Navigraph, it CTD when I am loading a new flight with a Navigraph flight plan often, especially with the CRJ planes. If it does load the simulator, the graphics is slow and the simulator will CTD in mid flight. When I remove the Navigraph folders and flies from the community folder the simulator works just fine. Fwiw I have updated all the Navigraph folders, including Navigraph NAVDATA Center app . Any ideas and suggestions?
