Site not working - wordpress's fault?

[Neurosylum]

Hi, my site: http://neurosylum.pcriot.com isn't working. I think it's from trying to install wordpress's files from their site (unsuccessfully, that is). I'm so frustrated right now, I think I'm going to drown my anger with ice cream. >_<
Edit:
Nevermind. After deleting the subdirectory /blog that held all the wordpress files, my site started working. What is up with wordpress?????? >_<
