Subscribe plugin with category support

I have had huge problems with Subscribe2 not working correctly and it totally breaks in a MS installation. The Subscribe by Email plugin here works great but is very limited. Can anyone suggest a subscribe plugin that functions just like Subscribe 2 but allows for category support when a user logs into their profile?

I have tried the auto-chimp and other plugins to no effect. I need a self-contained solution within WP.

Thanks for any help you can offer.
