Cannot log in to SanDisk Ultra Backup 32 GB

Hi, I have been unable to log into my backup SanDisk Ultra Backup 32GB ever since I switched laptops. When I insert the USB drive, it does not launch the login. When I try to run the U3Installer (even from another website), it asks me to log in first. But I cant get the login bit to launch. I am on Windows 7. Please help.

To install the Windows 7 U3 upgrade you have to run it from a nonWindows 7 pc.  Windows XP would be a good choice.
