Free store in Cydia isn't working.what should i do?

I have a jailbroked Iphone thats ios 5.1.1 and i got freestore from cydia. I downloaded an app from the app store and it worked fine. Then i bought something else and it charged me money. And also one i pree the button with the cost on it in the app store it says buy app instead of download, which with freestore it should. Does anyone know how to fix this?

Use the other free store for apple its called instaleous and the URL to type in on cydia is cydia.hackulo.us
