Whenever I try to use the cameo generator, the above mentioned error shows. Tyler Adams managed to fix it by reinstalling it. I've already uninstall/reinstall several times already and it still acts like a dick.

What is going on?

EDIT: I can use it normally, its just that the preview is FUBAR and every time I type something or change an option the "invalid filename" error window shows up. Otherwise, all is good but annoying :S
