2GB limit reached, but cannot make a push to reduce repository size

[Fireside Games]

We recently reached the 2GB repository size limit. I found the culprit files, however when i either try to delete them directly from bitbucket, or remove them via sourcetree, i am denied. 

Source tree gives this error: 

git -c diff.mnemonicprefix=false -c core.quotepath=false -c credential.helper=sourcetree push -v --tags origin refs/heads/master:refs/heads/master

Pushing to https://firesidegames@bitbucket.org/firesidegames/benjamin-fishing.git

Completed with errors, see above

BitBucket simply gives the error: We had trouble committing your changes.

Thoughts?
