Vista Wubi uncompressing-install-uninstall-reinstall problems

[Tom]

I have installed Ubuntu within windows Vista and after it rebooted during the install i received an error message about mismatch between file sizes. Afterwards it restarted and i tryed to uninstall Ubuntu from Vista to reinstall it. But the uninstall exe doesnt do anything. I have tryed to redownload the uninstall exe from the oficial site and it didn't fix the problem.
The Ubuntu is 8.10 AMD 64
The Windows is Vista Ultimate 64 SP1
I have tryed to install Ubuntu on a empty separate NTFS partition with 30GB free space.

The instal didn't left anything in Start\Programs, the F:\ubuntu\Uninstall-Ubuntu.exe dosen't do anything, the add/remove from control panel is the same, I got no config.sys or config.bak in C: .The ubuntu folder in F: has 28.6GB, the partition has a total of 30.6GB.
