Actually it happens since 29th May 2007. All of my sitemaps have errors.
I don’t know how this thing can happen. Here is the error which I got from Google Webmaster Tools.
Anyone knows how to fix this problem? I’m not sure why my robots.txt is unreachable. I didn’t block the file in .htaccess.
Btw here is my sitemap for this site. I use a Wordpress plugin to generate it for me. Maybe the way the plugin coded the sitemap make the error. Not sure though. 
Edit #1: I think I know why I got the error text. In my robots.txt file, I accidently blocks any files with extension .txt from being access by Google Bot. That is why Google says my robots.txt is unreachable.
I have removed the disallow .txt from my robots.txt. Hopefully, the red error text will be gone forever. 
Edit #2: Still the same. Google bot can’t reach my robots.txt file and give the same error. Now I’m trying using the second method. Ask my hosting provider.

Your sitemap is working fine, Cypher. I am loking at it right now and there’s so error.
No error, i meant…
i think i had make a mistake in my robots.txt file. i was accidently disallow .txt. but i have removed it and let see whats happen next.

Erm..

Buat camni.
User-Agent: *

patutnya robot.txt yang baru ni xda masalah. kecuali yg sebelum ni memang ko block..
site map tu cuba generate pakai google pny. buang semua yg lama buat baru.
