I'm not Sensei, he allowed me to use his account.
I have an AMD Athlon 1GHz and an Nvidia GeForce FX 5200. I installed the drivers (version 163.71) but BL doesn't start, instead it gives me "Blockland.exe has encountered a problem and needs to close..."
Badspot (I think you're the author of BL?) maybe you should code some print statements so that when someone starts BL from the command-line people could see the errors?
