admin what will i do i re download the client many times...but i cant play the infinity..it says that Client closed, muguard case 007, muguard system file missing.
Then you haven't installed the client successfully or maybe haven't download it successfully. Try to download this patch http://dll.infinitymuonline.com/patch/InfinityMU%202010-05-10%20Patch.rar and extract it over InfinityMU client. If still not works for you then re-install the game or re-download and then install.
