This issue has been resolved (see last reply in this thread)
Right now all revisions of TopoFusion Pro have a problem with certain ATI video cards (examples: ATI Radeon HD 3400 Series, ATI Radeon HD 2400 Series). The problem is that the 3D model appears black, though 3D tracks and waypoints work OK.
At present this appears to be a driver issue, not a bug in TopoFusion. A ticket has been opened with ATI and we will continue to monitor this.
Please note, this only applies to 3D mode -- 2D and all other functionality is working 100%.
Thanks for the patience.
