Won't get past login screen [RESOLVED]

[Slicksilver555]

Today I downloaded the game and opened it, and it got to the login screen (although it said Invalid Authentication Token). Since a friend told me to download it, he linked me to a topic where I downloaded a mod which enabled me to change resolution. I opened this and tried to log in, but the screen just went black when I clicked login. I looked at the console and it was flooded with errors. I updated JRE and tried to run it again, but got the same problem. The error was:

See below.

I figured it out. My system time was behind by a few seconds.
