the laggy and unstable stuff is on your part because it is exacly the same file as posted on here. to reduce some lag etc go read the forums, there are posts that explain how to reduce lag by changing some options.
so for the last time for everyone: If you can't wait for the files on here, download it at realmstock (it's from 059) it's the same client, same maker etc.
it has been working for me every time but u just need to delete the cookies.
when the files here are approved come back to mpgh.
This is the most easy way and fastest.
