From what I recall, you do not need to re-apply, but I will poke and find out.
Just the same, it wouldn't hurt to go to http://accounts.wizards.com and check to make sure that you are opted in to communications.
Note that I can't actually see the instructions from the vt page because I am a member, so if someone could copy/paste them, I would greatly appreciate it.
The page at Dungeons & Dragons Roleplaying Game Official Home Page - Tool (D&D Virtual Table) says:
D&D INSIDER
DUNGEONS&DRAGONS
VIRTUAL TABLE
The Virtual Table beta is live!
