Farewell...

Don't close my thread nothing's solved.i just found out the client only works with loopback adapters...and i don't have them,and if i will install it...i won't be able to play on another servers which i really want to play.i rarely get on my bro's account so yeah i won't be installing it.i will be on forums on chat box and of course...on MypleCraft :3

1.i DON'T have windows 7 i have a fucking windows XP.
2.Microsoft loopback adapters are USELESS.
3.I Can't enable/disable them because i am not ADMIN.

I feel really bad for you. :/ I hope you can play soon.

Does that not work for you at all? (Sorry can't post links yet) Not even if you completely uninstall the adapter first and then reinstall?

Or does it not work because you lack sufficient admin privileges? If so, is it possible for you to ask whoever does to install them?

Microsoft Loopback Adapters sucks.i don't have the permission to disable them/enable them.so if i was an admin and the problem was that i didn't had loopback adapters then it will be an another story.

Well we do have some guides here that can help with your problem if you can become an administrator on your computer. You should check them out.
