Why suddenly I could not open my site

Last night I forgot that I hadn’t close the editor in my desktop when I went to edit the unfinished new post in my laptop since my graphic program was there. Once I published my new post, turned off the laptop I went back to find that the editor in my desktop was still running. I closed the editor and try to open my page but the only thing I could get was my header. This morning I woke up and tried again, still the same. It’s http://28oktober.net . Yes, it’s oktober with a ‘k’ not a ‘c’. I recycled the power, deleted the cookies, but it was still the same. Called the ISP, they told me that my files were gone. Fortunately, when I tried to open the editor from my desktop, the files were still there. I could push the ‘visit site’ button to see the latest post as well as visited other pages, but I could not open the front page. It looks like something wrong with my index page. Any suggestion? It you could not open http://28oktober.net , you can try other page, such as this one: http://28oktober.net/2008/05/25/bahaya-beta-blocker-dalam-operasi-jantung/
I can see them but could not open the first page. Any suggestion? TIA.
