Are you possibly using a Vista or a Windows 7 machine? If so, you may need to uninstall and reinstall both Fusion and the drivers. I think Edge has said Fusion won't work on Win 7, but some people have reported success.
Try uninstalling Fusion and then uninstall the drivers. Here's a link to the driver uninstall procedure.
http://forum.gopowerhungry.com/faqs-...tallation.html It was written for Pegasus, but the general process would be the same for Fusion.
Then, reinstall Fusion, start it and plug in your Evolution (in that order). This may get things working.
If it doesn't work, and you are using a Vista or Win 7 machine, try to find a kind soul with an XP machine.
