Hmm… I remember buying the license for ST2 back in the days and it specifically saying it’s for ST2.x only. However, it also worked for early ST3 versions but stopped working at some point. Which was when I’ve switched to something else.

After having been shafted by sublime text I will never believe anything called a “lifetime subscription” is such.

Care to elaborate?

AFAIR SublimeText licenses are always only for a specific major version. And they sometimes might work for the next major version. So, I guess you’ve just installed a newer version for which your lifetime license isn’t valid anymore.
