Does EMS have IP block?

I play KMS, and i want to try either GMS, Maplesea, or EMS on the side for fun to try and enjoy the game in english. I tried GMS and Sea and couldnt get it to work. Does eMS have ipblock? also When you download another version of maple when ua lready have KMS downloaded on ur comp, do u have to change any names of files so it doesnt get mixed up?

Yes, EMS does have an IP block. As for the installation directory, you might have to change it depending on where it goes to (I don't know where KMS installs to). For example, GMS defaults to C:\Nexon, while JMS defaults to C:\Program Files\Nexon.
