I have recently purchased the withdrawal add-on and had it working ok with the API key. Unfortunately, I had to restore my wordpress site to backup which was before I integrated the withdrawal element. Now going back to reinstall the plugin and integrate it with the same API key, I am getting this message on wordpress:

Cannot activate API Key. No API Resources available.

I have tried completely deleting the parent plug-in (TeraWallet) and reinstalling but nothing seems to be working. Any help would be greatly appreciated!
