Controller is not working after 5/17 update
Perhaps, your controller is set to work with only the 32-bit client, and now you are using the 64-bit client. This happened to me.
You can read more about the two clients in the 64-bit Client FAQ Sticky found in the Account Support sub-forum.
Good luck.
I tried and it work!
Yes, you are right, I set my client as GW.exe only.
After I set the client as GW-64.exe, my controller work now.
Thank you very much XD
Happy to have been of assistance! =)
