Error registering Envato Elements token

When I try to register an Envato Elements token on my website, I get an error message “Sorry something went wrong, please try again.”. I assume that it could be because I previously registered a token. I can’t find where to reset that token. All other Envato Elements options on my website display a blank screen. I have already uninstalled and reinstalled, but no improvement. What can I do? Thanks.
