Why Isn't Google Play Opening?

[AC Question]

I have a Lenovo a1107. I installed Kingo Root, but then I factory reset because the SuperUser App would crash when trying to open it. Now after the factory reset (multiple times), the Play Store will say "Server Error" then crash. Every other application works. Also, "com.google.process.gapps" used to crash occasionally, but I disabled an app and fixed it, although I forgot which one. I recently installed Framaroot and chose to uninstall root, and it said it worked. I still wasn't able to open it.

Something was modified and needs to be reverted. If you don't know what was modified then only restoring the device to factory, if the factory firmware is available, to get it back to stock.
