Carlos,
I don't know if it has anything to do with it but you should not put ANRB in program files as the Windows virtual store causes problems. I believe that the V5 full install default is outwith but if you do the upgrade this goes to wherever previous version was installed.
If it were me I would uninstall including manual deletion of orphan files and reinstall to somewhere like C:\Airnav.
If you decide to follow this advice also remember to save folders like silhouettes, outlines, Logos etc and also my log and insert into the new install.
