UDK Error no lights shown not even on starting box

[fmetal]

im using Nvidia 7600gt with latest driver and i get those when i open the UDK (1.7 beta on last beta not even textures were shown)
the textures are there... i dont get to see the lights for some reason.. not even when i press play ! i try to build them but nothin!

I guess you've got a low end pc, with my low end pc i have the same thing but only if i use updated drivers, i use an older version of Nvidia, i think it's version 285. something, i can't recall what it is ....

I uninstalled Nvidia Drivers and im with windows one and works like a charm thnx !!
