I had the same problem, also in Reloaded.
And I'm not using dial-up.

I had the same today when using my pda to view a PM. But I just logged in and then everything went fine. Weird thingy...

I got the same error as I was reading the forum without beeing logged in and clicked on a link which pointed to an other thread in this board.

It was in one of the guessing game threads ...

Well, if you are a guest, and trying to follow a link to a hidden forum, then yeah you won't be able to log in.

Recently a number of spambots were IP-banned. It might be that you are connecting through a dyn-IP server and got assigned one of these IP's.
Check your IP number when this occurs and contact Tom later telling him what IP is that.
