If you're using a clean copy of your client, most servers on that list have their own patch files for clients to use. If you patched your client with the files from P99, forget about playing on any other server, until you reinstall a clean copy, or use a clean backup copy of your client.
Before trying to log on to any server, you would need to find out what files (and client) you need for each individual server. many servers can, and will be different. You would have to get info on each server and find out what client they support and where to download their supporting patch files.
