installing Voxin on a thumb drive

[Lenny]

Hi All,
I wrote in on this problem earlier, and had no solutions offered, so I 
thought I'd try again.
I installed Ubuntu 10.04 on an 8GB thumb drive, with a persistence file of 
4GB, this was the 100% option in the Universal Pendrive persistence option.
It booted into Ubuntu okay, and I copied the Voxin 0.37 installation folder 
into the home directory from my windows machine, and in terminal, I went 
into the voxin-enu-0.37 directory, and typed the following:
sudo bash voxin-installer.sh
And I looked at the licenses with typing "yes", and when it got to the part 
where it asks if I want to use this in Orca, I typed "y" for yes, and when I 
pressed enter, it messed up my Orca that was running, and I used the 
shut-down option, and now Ubuntu is messed up.
I have also tried this with Voxin 0.41 with the same results, that is why I 
tried an earlier version.
Can anyone suggest a solution please?
Thanks in advance.
