Lumion FREE 2.5 has different (and in some ways fewer) restrictions than Lumion FREE 2.1, in terms of materials and models. You can even unlock more models by sending emails about Lumion to your friends/colleagues:

If people continue to abuse the
Lumion FREE rules we will probably have to tighten the restrictions even more, e.g. with a full screen watermark. There's more information in this thread:

It only seemed to occur in a particularly complex scene, and he hasn't reported any problems since then. However, since you can't save the scene I am unable to investigate your report in more detail.
My advice would be to recreate the scene in
Lumion FREE 2.5 and try to render it again.
If you're still getting the dark frame glitches, please upload the 2.5 scene, and I'll try to reproduce it.
