But, unfortunately, I am not. The plugin was downloadable through XenForo Resources and now it's moved to an external server, where registration using reCaptcha is not working, so not possible to download the upgraded file.
I think the best solution would be to use the contact form at that very server and tell them about it or ask for help? There is nothing anybody can do here to help you.
I also just tried to sign up right now and could get past the default Xenforo captcha without problems.
