I finally figured out how to get credits from the above game, but it took 4 hours just to get 133 credits!
I have a new problem, I uninstalled the above game and now when I go to the tapjoy offers, the "install" and "new user" buttons are inactive for all the offers. I cannot install anything from the offers page. I tried installing "Woodoku" game using the google play store, but I cannot get credits for installing it with this method.
I have tried 2 different android phones and an emulator on my PC. The daily 75 videos still work, but tapjoy has somehow become disabled.
