yeah but it wouldnt have the moderator bits i installed for...well me being a moderator
Minecraft.net and your client launcher both run from the files saved to your jar (
I believe) so optihelp ect. should all be there if you were to try in the browser, I'll check then edit this post to see what happens.
Minecraft.net login servers are down -confirmed- so ya might as well just hold off till they're back up.
Unless I literally cannot because of this.
Edit: I got black screen'd on minecraft.net first attempt.
