Endnote X7 in Mac "Retrieving Records" All the time! So ANNOYING!!!!!!!!!

Why is endnote X7 syncing all the time, so that I can’t even use the reference anymore? 

Not responding a lot of time, need the right timing so that I can actually use endnote? 

using mavericks, endnote x7… 

saw the thread of similar problem last year, still without any update??? what is going on??
