Just downloaded latest wubi and am running winxp pro sp3. I have the same problems. I have the latest ubuntu iso in the same folder as wubi with no other files. When I run I get "pyrun.exe - No Disk" for my DVD drive (drive E).
If you are very very patient however, clicking Cancel (50 times?) eventually wubi loads.
