When something doesn't work as it should, things can become stressful very fast. This is why you should be mindful of all the trouble spots beforehand.
Knowing where to look, what it should normally look like, and what an actual error looks like, helps determine the severity and accelerate the repair.
Most problems can be solved by searching on Google. A useful Google search is:
(vCD OR vCloud director) [Search words] or for vCNS (vCNS OR vShield) [Search words].
Other really good resources are the VMware Communities. I would encourage you to sign up (its free), and then you can search for answers or post your questions, and you are likely get help from them. VMware Communities can be accessed at Communities.vmware.com.
As you purchased vCloud Director, you have their support. Call VMware support for any help you require or go to www.vmware.com/support/.
If everything else fails, remember...
