Envato toolkit won't connect to API

Hi Everyone,
I am trying to install the envato toolkit, but after generating a token and testing the API, I get the error

“The OAuth Personal Token could not be verified. Please check that the Token has been entered correctly and has the minimum required permissions.”

I know I have copied it correctly, so I guess it is a permission issue.
Any suggestions on how to fix this?

Thanks for any help you can provide
Scott
