Cannot install Ubuntu Server 9.04

[realchamp]

Hello. I have an old PC.
Specs:
AMD 2.0GHz
512mb RAM
60gb HDD

I use Ubuntu Server 9.04 32bit. Whenever I try to install it I get this error:

Warning: file:///............... was corrupt. And afterwords I am not able to install further. I've set the HDD to ext2 and mount root to / .

Since it is an old PC, I was wondering if it might be because of my CD? Since it's about two years or more old and the PC is like 5 years old.

Never mind. I figured out it was the CD.

I changed it to an older and it worked.

- Problem solved!
