In order to use the sandbox you have to patch to v0.3.0.14093 right? How do you patch your client? I tried the Blizzard downloader/updater in the support folder, but it says there is no patch to apply. What do I do? Reinstall the client or something?
EDIT: sorry, used the wrong .exe and wasnt patching... please delete this
