e out of memory

I have brought ADT drawings into Viz in the past w/ no problem - applied materials, added lights, cameras, the works w/ no problem. And I can go back to some of these and they still come into Viz nicely. But I cannot draw a simple new scene from the beginning and bring it into Viz without getting an errorcode "eoutofmemory". Help!!!! I'm using ADT 2007, but still have ADT 2004 installed.

Not sure, but I think I remember this being a directX problem... Not sure how to fix it (aside from making sure you have the latest and greatest directX), but I'm throwing it out there as food for thought.

Hope this helps.
