I am testing OAuth integration with my App. Everything was going fine until over the weekend I lost my refresh tokens for my test accounts.

Now I am receiving this error:
{"error":"invalid_grant","error_description":"expired authorization code"}

The redirect back returns a code. This code never changes. However, this code is deemed expired once I try to request an access token and refresh token. I imagine this is because the initial access token has expired and I need to use the refresh token to gain a new one. However, I do not have access to the original refresh tokens.

My question is, how to I reset this whole thing? I have tried the following in all possible combinations:

- In the client login, revoked oauth access to all apps
- In the client login, Reset API Key
- In the developer login, modify redirect_uri
- In the developer login, completely delete exisiting app and create a new one. The new app gives the same error.

I would just like to get both the Client Login and Developer Login App reset to square one. Then I can request my access and refresh tokens and, this time, reliably store them.
