here's an oddly specific program i need help with getting the hang of:
terragen classic. planetside software's
terragen isn't exactly obscure, but i recently downloaded an unregistered terragen classic from oldversion.com, and so far i know some of its ins and outs, but there's one thing i'm struggling with: rendering animations
unlike keyframes, which modern terragen uses, classic uses "scripts". but i don't know how to make animation scripts, and when i try to load or render a script, i get the error pop-up attached below.

what should i do? i'm on windows 7, and i want to try and make this program work. any help would be appreciated
