Maple Strange Login Problem

Zenith is a new server right? Maybe it's not configured like the other ones. You may run into problems when they do more maintenance on that server in the future. All the 'established' servers + the cash shop server don't let you in, right? The shared IP sure is giving you problems.

Any way to use the net on something else so you can test how your internet performs? All your other settings fine, such as firewalls/antivirus?
