AudioJungle’s videohive questions

I have Imovie 11, Motion 5 and just downloaded FCPX.  I have a few animaitons and logo reveals that I really like on audiojungle.com in the videohive section.  Most of the ones that I really like say they are After Effects project files.  Ok since its almost $250 a year for a single app purchase in Adobe for AE, is it possible to download the ones i like that are AE project files and still use them in Motion5 and FCPX?  Or do i have to waste the 20$ a month membership just to use the files from videohive that I already have to pay for?
