Some geometry & trees missing from AccuRender Walkabout Window and Renders

I seem to have hit a problem with AccuRender 4.0 and AutoCAD 2007.

Some of the geometry seems to be missing occasionally from the walkabout window, I have a set of curved stairs on a model and they keep disappearing although I can see them in AutoCAD, just not in AccuRender, needless to say, they do not render either if they do not appear in the walkabout window.

I tried inserting some trees the other day, although they appeared in AutoCAD, they were missing in the walkabout view and did not render either.

I have tried reloading and auditing the drawing, no errors are detected.  I am at a bit of a loss here.

The only other suggestion I have found is to update to the latest nVidia drivers.

MACHINE SPECS ARE:
2GB Corsair Platinum Dual Channel RAM in dual channel mode
AMD Athlon 64 3800+
Geforce 6800 GT
MSI K8N neo2 motherboard
Western Digital 500GB HDD
Windows XP Home SP3

I believe the nVidia Drivers are out of date however.

Any help appreciated, thanks

Thanks for the suggestion, I tried upgrading the drivers and it didn't seem to have an effect, I didnt think of downgrading them though. Anyway, I dropped a line to McNeel & Assoc.  They got back to me with the following:

"Unfortunately this is a bug in Service Release 3 of Accurender 4, blocks won't show up in AutoCAD 2007. At the moment, the quickest fix to this problem is to roll back to Service Release 2 of AccuRender. To do this you need to uninstall AccuRender 4 and install it again with Service Release 2."

...Sounds like this may fix it so I'll give it a try and get back to you!
