This doesn't seem like a hardware issue so no worries there. And I updated the file today using RahiTuber V:14.410, so that should be fine as well.
Just to be sure, did you remove the old files before extracting the new ones to avoid any potential conflicts? And did you place the new files in the RahiTuber folder, most likely C:/RahiTuber? (unless you installed somewhere else)
If yes to both, then I'm honestly at a loss at this point. I'll be poking some of my friends to help me troubleshoot anything else I can think of but otherwise I may have to bother Rahisaurus themself.
Sorry for all the trouble!
EDIT: I've tested it on a friend's rig and they had the same issue. I've disabled downloads of the model until I can figure out a fix.
