firefly can't generate no video

Ok, can you please tell me what OS and browser you are using and their version numbers?

Thanks,

I tried a couple for free until I reached my limit. Still needed a few more. Got the plan, reloaded and now nothing works. Don't seem to have any support available...

Yep, no matter what I do. Same situation

Are you getting this when using a keyframe?  If so, does it work without a keyframe?
