Anti Splog white screen issue

I'm using WPMS 3, BP 1.2.5 with the BlogsMU1.0 theme & Anti-Splog 1.04

My site is relatively new and have just started receiving spam that was not detected by Anti-Splog. When I try and spam the individual blogs and click on the confirm button I get a white screen. When I go back to the Sites page I see that the blog has been marked as spam. If I select multiple blogs to be spammed the same story happens however only one of the blogs are marked as spam.

I re-installed the Anti-Splog plug-in but the problem still persists.
