How do I force my Java to work.

[ShadowAtlan]

So I've been playing Haven and Hearth for a while on my friend's computer, and when I finally got the opportunity to try it on my own computer, it repeatedly crapped out. I've uninstalled and reinstalled Java several times, restarted my computer, restarted firefox, etc etc. Anything I could think of, but it comes up with the same error, someone please help.

Here's the error log:

Is your computer calendar on the correct date?

My calender was a day behind, and when I changed it and started up haven and hearth. My first reaction was to scream "BALLS".
Thank you kind sir. It works.
