The newest update of Mercalli 2.0 SAL (to version 2.1) push me to install K-lite codec pack (exactly like entry level version of Mercalli discussed some time ago).
How do you download the update from 2.0 to 2.1? On the site it tells me to download from my original email link, but that link has long since expired. I didn't add the "extended download" option to my order because it seemed like a ripoff.
