Whenever i try to download the BIOS dumper it downloads but wont open. My computer cant find anything to run it and offers the ability "open with..." to pick but nothing i have will open it. What should i do?

You need to run it on your PS2. See this link for more information: http://forums.pcsx2.net/Thread-Guide-to-...s-over-LAN

You might not have 7-Zip installed in your system. It's a free application that you can get here:

Once installed you should have no issues extracting the Bios Dumper and proceeding with getting your PS2's BIOS.
