If you have vista, you'll need to run l2fork, proxifier, l2asrv, l2walker as admin and compatibility for xp sp2, you will also need to run the bakeice client as admin, you will also need to not only replace the host file, but as well add the same lines to lmhosts.sam in the same folder as hosts. If ur getting crash errors. Do a full chek on our backice folder and use the clean system folder from the guide post. this folder needs to be located in your l2 folder.
