We just got word from the DICE Development team that they are working on the 'Wall Hack' Fix right now and should be releasing a patch sometime soon that will patch that hole.
They are also working on the many sound problems many of you are facing. So please hold on and be insured that they are working hard for all of you. Please be patient with them. They hear your pain and are on the case. They are a bunch of great guys working their tails off for us. Be kind to them!
