License questions
 

Now before you guys start telling me to search the other topics and what not, I just want to say that I have done so. I am having a little bit of trouble understanding the whole license issue, as well as prices, renewals, transferrals, etc.

I am going to be purchasing vBulletin forum software from someone who is selling on another forum. What proper steps do I take in this? Apparently the license expires on the 26th of August. What would the renewal fee be and what exactly would I be renewing for? It says under 'Status/Type' that it is 'Active' and 'vBulletin 3.x Forum (Owned)'. Is this a proper license or am I victim to be charged a brand new license fee to be able to upgrade or download 4.0?

Hoping that my questions get answered soon. Thanks guys!
