Play Store not working after upgrade

Mar 27, 2014
Friends, Need help please.

I have a Xiaomi MI3 with following details..

Android: 4.4.2
MIUI: 4.7.4
Build Number: KVT49L

I upgraded to the above version just now after downloading the ROM from this site.

Everything works fine.. Xiaomi Market also updated all relevant apps. But 'Play Store' doesnt. When clicked to open, it opens up but a circle in the center keeps rotating.. as if its connection issue. But every other apps works including internet via Chrome etc..

Kindly help to get over this issue. Thanks a lot.
