I can't update Subway Surfers or any application that I have from Google Play.
Due to some virus, I had to disable Play Store and had to add another account. After that probably I can't update anything. I do want to play Subway Surfers:Sydney.
Please go to Menu > Settings > Applications manager > All. Identify Google Play Services and Google Play Store. Click on each one of them then tap on Clear data/Clear Cache. Attach another account or the original account and try to perform the update again.
