"Double Click, Inc" and PeerGuardian 2 blocks Craftster

[Dreambelle]

I use a very common firewall/popup blocker/whatever you want to call it named PeerGuardian 2. Whenever I go to craftster only the background shows and nothing else. I checked to see if PG2 was blocking something and it said Double Click, Inc. Is this the new advertising that craftster is using and what access are they having to my computer since I have to turn off my protection just to get on craftster?
