I purchased IS recently and although my X-keys USB works with keyclone it doesn't work with IS.
Is there any way to set it up or any constraint? I'm running under windows 7.
Run the X-Keys software as Administrator. This is required because Inner Space runs as administrator, and therefore when it launches WoW, WoW is running as Administrator, and the X-Keys software can't work properly since it is running with lower permissions.
