Normally, VIs that you call (when you place an instance of them on your block diagram) cannot be "unloaded".  They exist in memory, ready for action, as long as the parent VI does.

If you seriously want to unload one, you have to call it dynamically (Use OPEN VI REFERENCE, CALL VI by REFERENCE, and CLOSE REFERENCE).  You cannot have any static references to it, only references by name/path.

Unless it's huge, or you have some other special requirement, there's generally no need for that. 

P.S. Nothing got attached.

I don't understand.  The VI you attached has nothing to do with unloading VIs, it doesn't even try.

It's not clear what it IS supposed to do.

If the name & password are not correct when it first runs, it stops the whole program, including any parent VI.

If the name & password ARE correct when it first runs, it loops and loops (at 3.3 million times per sec on my machine) waiting for you to hit the STOP button.

You'll have to spend some words explaining what exactly you're trying to do, before anyone can help you.
