Norton Antispam incompatible with Office/Outlook 2013?

I have recently upgraded to Outlook 2013 (as part of Office 20123).

I installed the plugin for Norton Antispam, however Outlook disabled it because it has a detrimental effect on the stability of Outlook 2013.

Is there any news on when an upgrade will be available?

Thanks

I should say that I am using a new Dell AIO with Windows 8 64 bit and N360 Premium
