Hi,
You may have older drivers installed on this new Windows 7 machine. Please be aware that at this point, our software is not yet supported in Windows 7 but we do have a Beta USB device driver available for users to try.
Here's the Windows 7 User Group (where instructions for downloading and installing the Beta Driver exists, too): http://line6.com/community/groups/windows-7-public-beta-group
Until we have supported release builds for Windows 7, we cannot guarantee trouble-free operating on this particular OS currently. We apologize for the temporary inconvenience.
Regards,
L6Perry
