missing vi.lib files

Hello, I am using the motion assistant with labview 2013 and NI motion driver 8.1. I followed the first tutorial to create my first project (using the virtual friver). But when genrating a labview code, I could not execute the VI was created since there are plenty of messing VI's from the vi.lib such as : -Configure vector space.flx, -load velocity.flx -loaad acceleration/deceleration.flx, -load s-curve time.flx, -set operation mode.flx -load vector space position.flx -start motion.flx -chek move compleate status.flx -read per axis status.flx -Motion error handler.flx Can you please help me figuring out what the problem is? THank you very much for your help and have a nice day.
