Yes, I believe you can, although you would still have to look for the Ledu Client & LeduIPChanger/MirConfig. Things may look a bit messed up, so you might have to edit the DB's, this is simply trial and error to get it right unless you know what you're doing. You could also use a different client, which would involve changing the IP's and Server name in the "ini's". This all may seem a bit strange to you atm, but eventually you'll get used to it, best ways to learn:
1. Look at BabyHacks Sticky "The one thread you will ever Need"
2. Use the Search Button, if you need to find something out, this always seems to work
3. If the Search button doesnt work make you're own thread asking for what it is you want, be specific.(make sure you do search before posting for help, or you will be flamed)
