Saint-XIV

Serious question, why am I forced to update to a newer version when I've had 0 issues with the version I currently have? I honestly don't get, this is the first program I've ever seen that bars me from using the files, codes, and executables I've had on my PC for a while now. While my internet was out for almost 24 hours I decided I'd test some of the stuff I downloaded a few days prior when I started building a new LO, but got ****ed over when I tried to run texgen and dyndolod and was told "This version has expired. Use a newer version"
