Installer crash after Atlassian Account password entered

Updating from version 1.6.14.0 to 1.8.2.2:

• I was asked to enter my Atlassian account info.
• entered incorrect username and password
• found my correct username, but entered in an incorrect password.
• was presented with a "Password has expired" prompt above the user and pass entry fields, which I dismissed incorrectly as an "incorrect password" prompt.
• left dialog window open and opened web browser
  • looked up my correct password via my LastPass account
  • logged into my Bitbucket account with correct credentials and then noticed the same "Password has expired" prompt, this time noticing it for what it was.
  • updated my password via the web interface (Bitbucket site)
• returned to the SoureceTree installer.
• entered correct credentials and hit "Next" button
• it appeared to have accepted my credentials and was continuing to the next screen (I don't recall what it was, sorry)
• got the crash message and was encouraged to submit a bug

Expected behavior: SourceTree installer would continue after entering recently updated and valid Atlassian Account credentials
Actual behavior: After entering valid credentials which happened to be updated outside of the installer, it crashed.
