I'm sorry for my bad english.
I will try to be perfect...
I use this hack and it's really good but, there is a little problem...BAN!!
It's very important be offline and spend all gold because if you don't do that, when you back on line you receive a message of BAN.
I make this and "open" all to spend all gold.
And after 1 week my Real Racing is perfect playing every day without problem.
Go online just few seconds to have new challengs , later go offline and buy all about is possible to finish all gold or have less than 1000.
Enjoy.
