Lost admin access to plugin SVN

I have somehow lost Subversion and admin access to my plugin on the WP plugin directory. Anyone know how I can regain access?

I’m trying to update my plugin (multipost-mu). While my profile shows me as the author (http://ww.wp.xz.cn/extend/plugins/profile/hungrymedia) I see no admin tab and SVN commits fail with “Server sent unexpected return value (403 Forbidden)”.

Any ideas?
