I ran into the same issue with my Traveler and the new universal driver install. Fortunately for me, I know Windows and PCs like the back of my hand.
First, uninstall the driver you have now in the normal method (not usually needed...but...)
Second, reboot to safe mode.
Delete the MOTU folder in Program Files (and/or Program Files x86 - in a 64 bit Windows) if it still exists.
Third, navigate to C:\Users\{YOURUSERNAMEHERE}\AppData\Local and delete the MOTU folder.
Fourth, open the registry (regedit typed into the start menu and press enter.) Click on Computer in the top left. Then press ctrl+f. Type MOTU then hit enter. Delete the registry key it finds. (The "key" is like a folder on the hard drive, in this program.) Be careful not to delete any keys that are universal to other programs or software. In this case, simply delete the MOTU value in the right pane instead. Press F3 to find the next. Delete. So on and so on until done.
Fifth, navigate to C:\Windows\Installer. Make sure you can see the "Authors" column in the right pane. Click on that near the top to put the files in alphabetical order with respect to the authors. Delete the MOTU one or ones.
Reboot and install CCleaner. Use it to clean the pc of unwanted files AND THEN use it again to clean the registry.
Finally, install the new driver and all should go very easily now.
If you need more help, let me know. And good luck...let us know how it is.
