I have just purchase the citation and the navigragh data base, love the plane without the navigragh data base however with it install the plane is un-flyable due to the nav data trying to update and causing low frame rates. I let it update and 50min latter it was only 22%. I have contacted Carenardo and got a response that had nothing to do with my issue. Some v-pilots are able to use the both together as I have research my problem, while others like myself are stuck with a program that doesn't work.
Any help would be great.
