System does not support const arrays in glsl

[svenone]

Well, according to the steam page, where i bought the game:
OS: Windows XP/Vista/7
Processor: 1.5Ghz - Low budget CPUs such as Celeron or Duron needs to be at about twice the CPU speed
Memory: 1 GB
Hard Drive: TBD
Graphics: Radeon 9600/GeForceFX - Integrated graphics and very low budget cards might not work.

And a Radeon 9600 is one or two generations below a x800 pro and a SM 2 card as well
