Issue with onPurchaseStateChanged

[i1j1k1]

Hello.
I have a issue: I bought the item in my application, and it was success. But in fact my function for purchase is never called. Every time I open my BillingActivity it shows me a window with text, that I have this item, and cannot buy it twice.
As I see onPurchaseStateChanged is never called. And BillingController.isPurchased doesn't work in my case. I have read all topics with the same issues, but I don't understand, why it can be.
Please, tell me, what I can do to fix this.
And thank you for the library.

UPD: There is "W/BillingService(14265): Remote billing service crashed" In the logcat. Can my issue be because of this?
