Okay Beta 77 patch 4 has been released. In patch 3 we removed the 64bit JRE requirement, but now it has been reworked and re-instated in a way that I feel will lead to the best results. If you're on a 64bit operating system, RuneMate will prevent you from logging in if you're not running a 64bit JRE. This is because it has been shown to offer a much better experience. If you're on a 32bit operating system, RuneMate will allow you to proceed. However, if the game crashes because it cannot access the memory that it requires (which is an occasional occurrence) it will inform you that this can be resolved by upgrading to a 64bit operating system.
