Dead Client (Been offline for a while) : General & Trouble Shooting

Hola! My subscription doesn't expire until July 15, 2007.

I've been offline, out of the game (EQ2) for a few months.

Nowadays, when I try to update/run the client, I'm seeing -
Patching Complete...
Connecting to XUnleashed...
Authenticating User...
Invalid Registration
Code/Password supplied
ERROR: Unknown protocol used, reporting...

Since its been a few months, do I need to update/delete any files?

... and Nevermind!

Re-downloaded the client, re-patched, re-locked my registration code, and somewhere during all that, XUnleashed decided it liked me again <heh>.
