BEX just spinning after SPS16

We recently applied SPS16 to our BI system and the BEX Boradcaster has been behaving strange since then. Sometime the Broadcaster will just spin when we click on a report and then try to send an email. Also somtimes the Broadcast will work fine but the moment we save it as a bookmark then we cannot Boradcast it again out of the Bookmark. Tried and tired of it. Please help.
