Cannot install any hack clients! Help!!

Hey guys, I'm new to this forum. So I've been trying to download Nodus, I've followed the instructions but....
When I hit new profile and the part where I click release 1.7.4/1.6.4/1.0 etc... I cannot find release Nodus.

Please help me !!

Try ticking the "allow use of old beta", "allow use of old-alpha" & "experimental snapshots" boxes in the "edit profile" menu. If that doesn't work, you probably didn't install it correctly.
