Follow this procedure and let me know your results.
Download the v3.60 Edgeport driver package here:
Save the file to your desktop and double-click it afterwards. Extract the contents to "c:\temp360" instead of "c:\temp".
Download the latest Edgeport Configuration Utility here:
Save the file to your desktop and double-click it afterwards. Click on the Advanced tab, then click the Uninstall button. Reboot the PC afterwards.
When Windows loads, a found new hardware wizard should appear (if not, make sure an Edgeport is attached).
Choose "No, not this time" if prompted to search Windows Update for the driver. Choose "Install from a list or specific location (Advanced)" at the next window. Select the "Search for the best driver in these locations" radio button. Uncheck "Search removable media" and place a checkmark by "Include this location in the search". In the location field, type "c:\temp360" (without quotes) and click Next. Choose "Continue Anyway" if prompted. You may get multiple wizards - if so, just repeat this procedure until no more wizards are presented.
After going through all the wizards, you should get a bubble stating the hardware is installed and ready for use. Verify you are now running v3.60 by opening the Edgeport Configuration Utility (click start, click Run, type "edgeport", then click OK) and examining "edgeser.sys" under the Version tab. It should read 3.60.8.
If you'd like, you can safely delete the edgeport.exe and ip4n5360.exe files from your desktop now.
