Badspot won't completely revise the game just because one user is too poor to buy hardware good enough to run the game.
Plus if you have trouble recording Blockland you need a new computer anyway.
I am unsure if Blockland works with Direct3D as I've heard, Direct3D is new?
If you actually have a Direct3D only card, your computer is probably too old to run Blockland. Or anything for that matter.

nothing more can be done other than updating your hardware
Direct3D is old stuff.
