Change subversion password

Hey all,

I'm still using the beta version of appcode. My subversion password changed a few days ago, but now I cant manage to change it from within appcode. All the subversion commands I try to perform result in an error something along the lines of... "User cancelled authentication".

No matter what I do, I cant seem to just have it reprompt me for a username/password.

Any help would be appreciated,

Thanks
Craig
