I had the same problem once and this is what i did:

1. Contact Club Penguin and tell them about the problem.
2. Club Penguin gave me a program to download it and run it.

Then restart your computer and clear your cache!

Bad Connection?

Thanks!

Hello fellow penguins! I occasionally have that problem. I know exactly why that happens. Once, I tried to join this server, and it kept loading. I immediately logged out. When i logged in again, i saw that the server i tried to log into was full. So, the reason is that sometimes when you log in, you clash with other people logging in, so the loading cache is stuck. Try to go to less packed servers. One more thing, how on earth does everyone know me?
?

That is what happen to me too! Clear your Cache and by pressing F5 ( Refresh. )
If you login and you select a server and it is taking so long, go to Hibernate or other new servers! :D

Opps I made that sign! This one:

Get rid of all the tabs and go on it (including hacking programs)
then load if not get a new pc

Actualy its not the problem with your computer, if it goes Logging in (penguin name) forever it means a lot of penguins are trying to log on at the same time so what I do it just log on some other time. Occasionally you also have to clear your cache.

yea.......lolzzzz...

Check your internet connection. If it is down, reset your router if you have one, otherwise, you might need to contact your ISP (Internet Service Provider). If the problem proceeds, just know that Club Penguin lags a lot.

I would contact cp or restart ur computer
