Can't use SourceTree, keeps saying username/password incorrect

[shaddockweiler]

Hey Everyone

I've been having some trouble with pushing, pulling, and fetching on SourceTree. Every time I attempt to it asks me to login to Bitbucket. I enter my password, there is a pause and then 5 seconds later it asks again. After about 4 attempts it displays the error screen saying "remote: Invalid username or password" 4 times.

I've gone to the website twice and changed my password; each time reattempting to fetch or pull, and each time I get the same result.
