Hi Billy,
I found this little tidbit on a Family Search Help Site.
Currently we are not able to export data from Family Tree to a GEDCOM file. Use one of the Family Tree certified programs, i.e. Ancestral Quest, Legacy Family Tree, or RootsMagic to import data from Family Tree into one of the programs and then create a GEDCOM using the procedures above for the application you use.
Sorry I can't be of anymore help but if you need source information or have any other questions feel free to ask in the g2g section of wikitree.
Thanks for choosing wikitree!
