Hi,
Apologies for the delay in replying.
There doesn't appear to be any files in the attachment; can you try the following:
Download
http://www.displaylink.com/support/ticket.php?id=269
Once downloaded, please run it and select "Gather Support Information"
When you reply please select "Manage Attachments" from the "Additional Options" section below.
From there select Upload and navigate to the output of the tool which will be in a folder called "DisplayLink Support Files" on your desktop.
Thanks,
James
