Powerball is changing back to Continuum pr1, from pr3. If you were previously using both pr1 and pr3, you can remove the pr3 executable and just use pr1.

If you only have the pr3 executable, you can download the pr1 executable. Install it into your Program Files\Continuum directory, and update your shortcuts. PR1 EXE
PR1 ZIP

If you want to upgrade to pr3, use the instructions below. You will not be able to enter Powerball zone with this client. Download this file.

Extract the zip file to your Continuum directory (usually \Program Files\Continuum). WinXP can natively
extract from zips, otherwise download WinZip.
You will need to update your Continuum shortcut to point to Continuum039pr3.exe.
But be sure to leave a shortcut pointing to pr1 for other zones.
Here's a thread for potential problems.

For zone admins,
you will need the small update to subgame found below.
Simply extract the zip to your current server directory.
The next thing you need to do is hex edit the html in /version1/update.exe to point to an upgrade page that has 39pr3.
This will redirect users to the right URL when they hit "YES" in the new version dialog.
NOTE: Once updated, users will only be able to login with .39pr3
