Sorry, I read the sticky and stuff but I am still a bit confused. I played wow in china up to sometiems last year and I stopped. I want to begin playing again

Now my version of wow is at 3.0.5(9294) where do I go to update it to 3.1.3?

I been playing in china for the past 3 years but quit for over a year. Let me know thanks!!!!!!!

I am assuming that you are using a US/DE/FR or other non chinese version of wow. Unfortunately you will not be able to update your version without some patchwork, if you want to play with a non chinese version.

Follow the guide here on the forum, see link below, it might look a bit confusing in the beginning, but if you follow each step as mentioned you should be able to do it:
