Question [Q] Wechat not working?

Hi, I tried to install wechat on my Nexus 7 2012, on stock rom but every time I enter the phone number, it shows a black screen and returns to the starting welcome screen with the Earth. Any ideas?
Devices -
Nexus 7 2012 16GB Rooted, CM11 on motley Kernel with MultiROM running Paranoid Android, Stock Kitkat - KOT49H and Stock Jellybean - 4.2.2 as secondary Roms
HTC Wildfire Buzz A3333 - Rooted, S-OFF Revolutionary, CM9. Trying to cook my own CM9.
Galaxy Y - Rooted, Stock ROM

Yeah. XDA censors my name. -_-
HIT THANKS IF I HELPED!
Cheers!
