Based on the response in this thread: http://pokemon-online.eu/threads/35107/#post-484618 There may be a chance of it being an IP issue, some users can connect, some cannot (such as me for example, although I use the installable Windows Version to log in anyways). If possible, you can use the Windows version in the meantime, it's not a very heavy file and should download right away.
Thanks for the tip! I was using the webclient. I am currently installing the Windows version! :D --- Post updated --- Thanks for the help! I am enjoying it!
