Ah, that means that you don't have the license (at least it's not available). I've just checked, and if I try to launch the IDE when it can't get a license, I get the same behaviour. You'd get the same thing if you tried typing installDebugger() in the CIW - it will tell you that skillDev is not enabled.
We ought to have an error message telling you that it couldn't get a license, I agree.
I found CCR 1212069 was filed for this, and has been fixed for the IC617 release (not due until next year). It looks from the CCR as if the fix might get backported to an IC616 hotfix too, but there's no commitment for that yet.
