2 days behind? It is lucky for you, I got 6 weeks behind. But youvmust wait to sync it, wait 3 or 5 min and it will back to normal
If you have not updated in a long time, and are trying to update it now, it will stuck. I believe they were busy with some maintenance yesterday, however it should be done by now. My synching also got stuck for a while yesterday, but now it seems my wallet is fully synched. So try to synch it now, it will probably work.
