can't access my account

I live in China and I have been playing Hero Academy since Feb.
But about a week ago, I found out I couldn't use the international version of Hero Academy anymore.
There is a notice that tells me to update it, but when I search for it in the app store, they only show me the Chinese version.
According to iTunes, the English version is no longer available in the Chinese app store, which means I have lost the right the use the teams and services I  bought through the English version.  This makes me upset.
 
I hope there's a way to solve this problem.
Thanks.
