Since the sandbox issue has been up, we've found that our two sets of sandbox API credentials are returning that the account is inactive.  

When we try to login to the sandbox or reset our password, we get an error and can't log in.

These credentials have been used daily for YEARS and is important for our team to be able to train new clients in a staging environment.  We've been stuck like this for weeks.  

Using production credentials to get by isn't an option because we're using CIM, and we don't mix client IDs between production and staging.
