Stardraw Professional was discontinued several years ago and is no longer supported.
However, you should have no problem importing DWG into any of our current products e.g. Stardraw Lighting 2D, and the Martin Audio library is available in Stardraw Audio, Stardraw A/V and Stardraw A/V Lite.
The full list of current design/documentation applications from Stardraw.com can be seen at http://www.stardraw.com/Products/Pricing.asp and upgrade pricing can be calculated at http://www.stardraw.com/Products/Upgrade_Pricing.asp
