I have two licenses. As I was downloading 1.3.0, I noticed different version #'s for each lic. Does it mater which software I use on the domains? I don't really do much with either site. In truth I bought my second lic. to support the site during the lawsuit. So what's the story?
If you're saying that one license let you download 1.3 and another lets you download 1.1 then, yes, this is important.
When you purchase a license you get support and upgrades for 12 months. After the 12 months you can still download the software but only up to the current version that was available before the license expired.
If you want to use a newer version on that license then you need to renew.
