See the thread @tom80H linked.
The thread contains download links to new versions to alleviate the problem. Updated builds will be available via the normal methods (plex.tv/download, etc) at some point (reference).
Read the thread before downloading and installing any of the PMS builds. Some users installed the new builds. Others fell back to older versions. Also backup your database before installing any of the hotfix builds.
