Cannot Find How to Update

After updating to OS 10.8.4, I’ve received a message that a plug-in has been disabled and Spamsieve is not operating. I can’t figure out how to update to a newer version. Information on the website says, “Click the Check Now button, and SpamSieve will tell you whether a newer version is available for download.” Where is the Check Now button?

Apologies if this information is already available, but I searched and couldn’t find it anywhere.

For Mac OS X 10.8.4 you would need SpamSieve 2.9.7, which was released on May 1. Ordinarily, SpamSieve will check for updates automatically. If you’ve turned off this feature, you can go to the SpamSieve menu, choose Software Update…, and click Check Now.
