WampServer

I can't seem to use the two of these together. When using Apache 2.2.14, if PHP 5.3.1 is selected, all services will start, but no pages will load, and after a few seconds Apache crashes out. It's fine when using Apache 2.2.14 with PHP 5.3.0. To be able to use PHP 5.3.1, I need to use a much older version of Apache.

Any ideas why Apache 2.2.14 doesn't like PHP 5.3.1??
