My HayDay keeps disconected when I tried to list my things on the roadside shop

I am using IOS 7.0.1, and hayday works perfectly until yesterday. The wierd thing is my game keeps disconected every time i try to list my stuffs on the roadside shop, or i try to get the money on the shop ; otherwise, if i only look at inside the shop, or buy stuff from others' shop or play on my farm, the game works perfect.

Let me state it clearly again: my farm work perfecly as long as i don't try to list anything or get money back frim the roadside shop. Does anyone have same problem? Please help me. thank you so much.
