Invalid access, unverifiable 'nonce' value.

Hi there,

I purchased the Plus version for the plugin, and am trying to use the delete account method, but whenever I try to delete an account, it gives me the following error:

{“status”:”error”,”error”:”Invalid access, unverifiable ‘nonce’ value. Use the ‘get_nonce’ Core API method. “}

Here are the calls we’re making to get to that point:

https://xxx.com/api/get_nonce/?key=xxxx&controller=userplus&method=generate_auth_cookie

https://xxx.com/api/userplus/generate_auth_cookie/?key=xxxx&username=test&password=xxxx&nonce=1edf6e05b0

https://xxx.com/api/get_nonce/?key=xxxx&controller=userplus&method=delete_account

https://xxx.com/api/userplus/delete_account/?key=xxxx&cookie=test|xxx|xxxx|xxxx&nonce=1104bfbc88

Is there something that I’m doing wrong?
