Win 7 X64, Nvidia and DisplayLink problem

[Faidon]

Hello all,

I would like to report a problem after installing DiplayLink driver 5.6 Beta
(and older versions) in a system with this configuration:
Windows 7 X64 with all windows updates (except latest SQL server)
Graphics:Nvidia Driver 266.58 on an ASUS GeForce 8800GT
CPU: Intel Quad Core Q6600
Motherboard: Gigabyte DQ6-X38

When trying to attach the monitor a pop up informs me that "the display link driver is not compatible with this os and graphics".
Furthermore i experience crashes when trying to right click on "my computer" and in some other menus. The outcome is that windows explorer is restarting and i cannot access these os menus.
Also a look in Device Manager shows that in GeForce 8800GT properties that
"Windows cannot initialize the device driver for this hardware. (Code 37)"
When i uninstall DIsplayLink drivers and reboot, the system comes back to normal operation.
I have attached the log file.
I would appreciate if you come with a solution for this problem.

thanks in advance
