Pe2k Server Connection Guide
Step 1-Downloading PO
If you don't have Pokemon Online, then you can get it at http://pokemon-online.eu/
Hover over the "Downloads" Tab and click the "Client" option.
Then click the download link for your appropriate OS and begin the download. If you get a message saying that the file may be harmful to your computer, don't worry, the file is perfectly safe.
Step 2-Installing and Launching PO
The installation itself is pretty straightforward, so I won't include that. Regardless, if you chose to make a Quick Launch icon, just hit start and it will be on your list of programs. If not, then you can still access it from the Pokemon Online folder, just go to wherever you downloaded the folder to.
Once you click on the icon, PO will launch. First, you should build a team in teambuilder, that way you'll be able to battle. After you finish your team, hit "go online" and it should take you a list of servers.
Step 3-Entering Pe2k's Server
After you make it to the list of servers, scroll down until you see a server called "Pokemon Elite 2000". Click on it, and you're ready to enter.
Alternatively, you can access the server by way of Advanced Connection, just type 188.8.131.52:5080
in the advanced connection box and you're good to go.
