DameWare and WHD

Okay, I must be missing something pretty basic.  We have DameWare 11.2 and WHD 12.2.  What is the trick to getting the DW integration to work? I have the DW links enabled on both assets and techs.  When I click on the icon next to the asset it just goes to a black webpage:

Firefox can't find the file at Firefox can't find the file at dwrcc://**.**.*.**?assetID=691&whdEndPoint=http://ithelpdesk/helpdesk/WebObjects/Helpdesk.woa/ra.

Thanks
