There's some issue with the Ubuntu CD on
D:. Remove it and run
wubi.exe standalone. It will download a preinstalled, compressed disk image (a little over 500MB) and install from that.
The other thing you can do is remove the CD, but use the ISO you used to create the CD. Just place the ISO and
wubi.exe in the same folder before running Wubi. (Make sure the disk in D: has been removed.
In terms of what the real problem is, [Errno13] doesn't give much information. It's found a valid CD, but fails to copy it:

You can search for related bugs - the CD may be readable but corrupt in some way... but no way to know for sure.
