I'm not so sure I fully understand your issue. 

Are you using a different email address to log into VideoScribe, and it is showing projects from a different account?

If you log into VideoScribe and it is showing you projects from another account it will be because you're using the same computer/ user that the projects were created on in the other account. VideoScribe will show any local projects saved on the computer when you log in even with a different account.
