Joomla Loop Login Problem

Simple job, we are having the infamous Joomla Admin loop problem. I won't explain this because we only want a Joomla expert to fix this who has a lot of experience with this specific problem. We can't login to our /administrator control panel. We've tried resetting our MD5 passwords in the database, tried editing our session_save_path in the [login to view URL], we've made sure our session save directory is writeable, tried flushing our cache and different browsers/computers, etc. Any questions, please PM me. Someone with fluent english/french. We need talk via MSN Messenger, Email or Phone. Thanks.
