Failed to Verify Certificate

[AppelStrudel]

I just downloaded the game today, and I cannot play it because my computer is giving me an error.

Here is the error:

java.io.FileNotFoundException: C:\Users\Strudel\AppData\LocalLow\Sun\Java\Deployment\security\trusted.certs (Access is denied)

I'm not very good with computers, but I have checked the time in the bottom corner and it is correct to today (10/28/2011).
I also have updated Java to the newest version.
Finally my audio and video cards are up to date.

Any help would be appreciated

I also have updated Java to the newest version.

And what version would that be, please? Just saying this doesn't mean much. There are currently several versions of Java SE being supported. I know HnH will NOT run on v7 at this point. I don't recall exactly what the error was with those that tried it, but I seem to recall some sort of security issue like this.
