Spring RTS Engine

Hello,

Whenever I try to host or join a game, on any map, this is what happens.

The game would start up as normal, with the loading screen and the background image. This lasts for maybe two seconds (stopping precisely on "shading") before going all glitchy (lines and artifacts, etc), then the game shuts itself down with the following error message:

"Incorrect/Missing content:

Error at position 151 when loading vertex program file ground.vp"

I've tried dialing down all the options, and reinstalling (with removing the registry data), I've also tried a working ground.vp file with no luck.

My specs are:

Toshiba Laptop P20
3.4GHZ Pentium 4 with H/T
1GB of DDR Ram
Nvidia GeForce GoFX5700, 128mb

Please get back to me, I'm very interested in playing Spring.

Thanks for your time,
Sid

Problem fixed, but now a new one:

Whenever I try to start the game using any map, and under any graphics setting (Zbuffers, etc), the game loads and starts up perfecty.

But;

After exactly 12 seconds, the scring flickers, then I get this wierd "double vision" happening, where everything but my HUD (GUI), is, well... doubled. This makes the game very unplayable, and I'm getting desperate. :/

Thanks for your time,
Gubru

However, in the chat screen during the game, as if someone were chatting, I get the message "No Pixel Buffer found
