swilliamson9 on "[Plugin: WP-Filebase Download Manager] File Browser stopped working post 3.4.3 update"

Hi, I'm fairly new to this but post updating our site to wordpress 4.5 Filebase auto updated and now the file browser doesn't work on the front end and in the admin dashboard. Any help would be appreciated.
Trying to remotely connect the the school and uncompress a backup file set to roll the update back. However I prefer wordpress and updates to all be current and don't want to have the file browser fall behind. Wed have quite a few plugins in use but all have been working fine until today.
Many thanks in advance
