Explanation point on the boot screen

[#1]

I got my x10 yesterday and played all day long. Everything was fine untill I try to upgrade the software.

I used Sony Update Service software and it give error at the middle of the process.

Now, I got explanation point on my screen when I turn it on. I can't do anything.

Any ideas, how to fix?

Thanks
