Fandom is Dangerous

Well. Yesterday I began work on my Pros fandom seasonal cards. As part of that project, I tried to install a new program to make it easier to export video frames. Hours later, after a cascade of technical issues and user errors, I had thoroughly borked my computer, and I will now have to reinstall the operating system completely. So be careful, everybody. No running by the pool, don't cut toward yourself, always hold the handrail, and in the name of all beloved tropes, don’t do anything silly whilst working on your fannish holiday projects.
