I had the exact problem with the redirect after the games...
It was solved for me after i reformatted
Before that though, I had tried everything. I cleared and reinstalled flash, I cleared and reinstalled shockwave, Cleared all my "Downloaded Program Files", cleared cookies in many different ways, and about a dozen other things, and nothing worked, until i reformatted my pc.
I couldn't even begin to imagine what the problem was, at this point.... All i know is that it works now
