This result is often caused by having the wrong license for the application, e.g. Trying to run VK5 Premium Collection with a VK 3.0 license.
If you are unsure what license you have, you can check your iLok licenses at www.ilok.com or contact us.
Also, make sure that you are NOT running ProTools 8.0.1. There was a problem with this version of PTs that rendered all conforming products unusable. Avid addressed this problem in the cs1 patch (available free on their website) and all subsequent versions of PTs through 9.0 are also fine.
