Can't create video in Standard Def WMV

[Wizco]

I can create video using Dashware in any of the listed formats except Standard Def wmv medium files size. When I attempt create in Standard Def Medium File Size, (small and large file sizes work fine, as well as the PAL WMV options) I get the following error:

Exception: Invalid media type was specified.
at UltraGauge.Render.Video.BuildMainConceptGraph (Project project,VideoProfile videoProfile, String destVideofileName, Double startTime, Double endTime)
at UltraGauge.UltraGaugeWindow.V(String)

I'm running Vista Ultimate 64 bit, Dual Core@ 2.66GHz 8 gigs ram. Dashware ver 1.0.5

Any ideas?

Thanks!
