Cant login to origin Plants vs Zombies Garden Warfare

Don't forget that you have the Origin client software intalled on your local machine, so just because it loaded itself doesn't mean that it has made the next step successfully, to connect to the servers, right away. 

I saw i dont have Origin installed,i reinstalled it and worked thanks :D

You're welcome, of course. 

Now i know what was the problem,once i accindentally(sorry for my bad english) uninstalled Origin,and just run Origin.exe,so it doesnt show its installed,it just updated. Thank you alot :D
