I got a "plug in not active" error message when I tried it, so I don't think you're the problem Brad.... at least not this time.

Looks like they retired Adobe Flash so this one might be gone forever.

here is the one I have been using.

You can input all you own gear ratios and compare two rear gears.

It no longer works on my windows PC, as adobe flash has been removed.    I now simply use the tremec tool on my cell phone...
