couple of questions
 

My situation:

Currently on 3.0 and bought only a one year lease which means i have to upgrade to 4.0. i want to get it professionally installed by the vbulletin people, coz i honestly would have no idea how to do it, nor the time and patience.

First question, since my 1 year licence runs out on the 10th of this month, if I just make sure to pay before then for the upgrade, will it just continue to be 3.0 until the vbulletin person does the upgrading? how does this work? im a little confused...
