How to use Sourcetree with two different BitBucket accounts?

[John]

I work for two different companies, each of which has a BitBucket account.

I have been happily using Sourcetree to manage the repos of Company A. Now I am trying to add repos to the BitBucket account of Company B, and I'm getting weird errors. The most recent one is:

Invalid client_id

This integration is misconfigured. Contact the vendor for assistance.

I suspect I'm not properly separating the repos on my machine for the two BitBucket accounts within Sourcetree, but I'm not sure what I'm doing wrong. Although tech savvy enough to use a repo, I'm not a developer, so I use Sourcetree rather than using Git in the terminal.

Any help is appreciated!

This is not an answer, but merely saying, "Me too." Our company was acquired by another company so we have two different Bitbucket accounts, and I have to work with both. It's pretty insistent that I am one account but not the other. 

It would be nice to have the same interface with both.

Also, under "Error Contents" the message, when expanded, is:
