Go to
http://www.lampwrights.com/showthread.php?t=261 and you'll find the updated plugin... and the patch to manually fix it for WP 3.3. You have to make manual file changes to two files but it's easy to do.
Also, it's easy to downgrade to 3.2.1 again. I'm testing the patch on my DEV forum and having a few Admin permission issues that still need worked out. So I downgraded my Production Forum to 3.2.1 again.
Just over-write the wp-admin and wp-includes folders and all the root WP folder files EXCEPT wp-config with 3.2.1 files.
Log in to admin and you will probably get an "Upgrade Database" prompt. Just click OK.
