XP11.50 not displaying latest cycle

Hi, fairly newbe so not too techy. I have a fairly standard windows xp11.50 set up with just the Zebo 737added. All was working well until recently. I have been using the FMS ok but it appears to now be using the incorrect cycle. I get an error window when loading the plan into the plane- incorrect cycle, Currently 2111 route planned with 2109 ( I understand about the mismatch in route planning I think) but FMS is saying my system is up to date with 2113 rev1. I also have the Zebo 737 with the Avi tab. I have uninstalled FMS and reinstalled. I have checked the file paths and the XP 11 is in the root directory c:\X-Plane 11. ( I did also try c:\X-Plane 11\custom Data). The Zebo is in …\Avitab\Navigraph.
I have had a look through the FQ and tried some of the suggestions but no luck. Can you please help?
