Help with opening files

Hello, I was trying to edit my server.dat for QoProxy and I set it from "open with unknown program" to "notepad". Now that I have changed it, it will not allow me to run Conquer because it says it cannot open it.

How can I restore it to the default setting?

I have Windows XP Home Edition SP2.

Any help is greatly appreciated.

redownload it or when the file is in the patch, patch it again

That didn't work :x

I've changed the actual file setting >.>
