Plutonium

Also from the update video on your site, i saw him close the server list and connect to online services (i can't do that either)

I just recently installed Plutonium, I went step by step and did what the site told me to do, but when I Join a server, i either get the error "Challenge verification failed" or Error UI69095 and my screen turns black and I have to close everything. Ive tried to update it, but im at the same version as my friend who can play fine. Currently, that version is core: r839 and launcher version is :2.2.1
I have it allowed through my firewall, and it was installed into its own folder.
