I've developed several ebay applications and generated tokens successfully with the DevID, AppID and CertID in my developer account.
However now when I try to create a new user token the Token Tool always fails with the message "Developer ID in session certificate invalid".
I don't think it is invalid because it's the same one I'm using with existing applications.
I've tried three different browsers, two different PCs and tried manual entry of the keys as well as selecting Key Set
Nothing works. Same error every time!
Is there another way I can generate the token or some other way round this? Has any one else had trouble with this tool?
