Hi, guys. need help on how to use the Blizzard Mobile Authenticator. i have purchase and download the application to my hp but i cant log in to battle.net server. any idea y this happen ? please reply. thanks in advance.

im also encounter this problem before. First make sure your phone have internet access, 3g/edge/gprs. If u still cant connect to the battle.net, reinstall the app. It worked for me. I uninstall and install again. It work.

Does the authenticator have any sort of expiry? I couldn't download it to my sister's hp because her gprs is not working and the hp shops all close (6pm).
