Ok, so I finally downloaded and installed linux on my own computer and i'm happy with it. My brothers have a 2003 dell dimension computer that has .5 gigs of RAM in it. XP was quite slow on it, so I installed ubuntu 8.04 on it. Only thing I needed to download was graphics drivers and 236 software drivers...

My brothers like to play on http://www.clinet.silabsoft.org
The first time I booted up the computer after the install, I was able to go on the site fine. Then when I restarted after all the updates, I get an error message. Link to a screenshot of the image is below. I'm guessing it has something to do with the cache, but I don't know how to fix it...

Picture of what I get

If someone could help me, that would be great.
