Can't import movie

hi all!
I’ve just buyed motor and I’m not able to import movie. When I go to new project motor asks me to import movie but when I go to import a movie from my library an error message appear: “fail to open the movie:check that the file is readeble”. I don’t know hot to fix it. (I tried to open file both from my capture scratch in FCP as from other hard drives…all .mov footage)
thanks in advance.
