Why did my TinierMe ring stop giving me stuff?

It started like 10 minutes ago when I was at a ring party. Towards the end, (people were coming in and out so I was getting tons of Chibi Coins) and suddenly, 5 new people came in and ringed me but I got ABSOLUTELY NOTHING except starbursts on our rings. Why the heck did my ring stop giving me Coins and stuff????????????????????????????????
