Clicksor site slowing down my site?

For somereason Clicksors ads have been slowing down my site greatly, the page would load all the way to where ads are and take a long time to load the ads then the rest of the page would appear, it seems it causes the site to hang.
Anyone know how to fix this or is this just a sideeffect of the server issues they are having?
(When I remove ads forum functions normally).
