okay so this was all quite complicated but here's what i did...:
(NOTE: I have the multiverse plugin and filezilla)
-download the world save zip
-took the folder out of the zip and put it on my desktop
-renamed the world save to worldb (make sure there aren't any spaces in the name)
-opened filezilla and connected to my server
-put the folder in the server (very front page works)
-opened minecraft and go to server
-type /mvimport worldb
-type mvtp worldb
NOTE: IF YOU DO THIS WITH MORE THAN 1 WORLD MAKE IT A DIFFERENT NAME EACH TIME.
-TYPE mvdel worldb if you don't want it anymore
