I had both Paypal Pro and Express enabled in version 1.3.8a and now I am trying to updagrade to 1.3.9 it will only allow me to use one Paypal module at a time! (Crap!!) I liked giving the visitor an option of either checking out without registering (espress) or registering first. What the heck is going on?

Which one should I use? Does express have the same features are Pro? Any ideas?
