Problems Patching

A couple things…

I have Democracy 2 Version 1.01 on my computer. Its been very hard hunting down Patch 1.23 but I managed to find it… is this an official patch and the most recent?

Second, everytime I patch it with any patch of any version from any site, it says patch failed and renders my game unplayable until I reinstall it. What should I do?

Lastly, just for kicks, everytime I merely click on the Veterans policy the game crashes… is this fixed?

Let me know - thanks!
