The problem is that the gravitational infinities one gets in QFT are non-reonormalizable. Renormalizable theories must follow a very strict criteria (and even then they are rather difficult to grasp if you don't really put a lot of thought into it).

I assumed that was the case, but it doesn't alter the impression I get about the situation. That still sounds to me like, "we can only apply this fix when instances of the problem follow certain strict criteria".
