I am trying to set up popup ninja and when I try to integrate with Constant Contact, the initial form fails with the following: OAuth Exception: Username withimpact not found in datastore Click here to authorize Upon trying it at CC, I get the following message: The provided request token to authorize must be valid. Please close the window to return to you application. I cleared my cookies and I still get the same message. I also confirmed I'm using the right username and password. Help please. Thanks!
