No puedo iniciar SL!!!

Saludos! este es mi primer post aqui.
Estoy hace mas de 3 semanas tratando de correr el SL, y sigue acusando problemas con la placa de video y no hay forma de hacerlo funcionar.

Antes tenia una Nvidia XFX 8500GT y no hubo manera de que pueda iniciar.
Ahora me compre una Sapphire ATI Radeon HD4850 y me encuentro con el mismo problema.
Tengo un Athlon 64 X2 DualC. 4200+ (2.21ghz), 2Gb de Memoria Ram, Video Sapphire ATI Radeon HD4850 de 512MB. Sistema operativo Win XpPro SP3.

Si alguien es tan amable de ayudarme estaria profundamente agradecido!
Saludos!

Sebastian.

El log de error te indica que debes configurar la resolución de video en 32 bits, el "unable to create windows" es un error típico cuando se tiene el video configurado en menor resolución que la necesaria para SL.

Asegurate de tener tu video configurado en 32 bits de resolución.

Tengo el video configurado en ambos monitores en 32bits y la resolucion en 1280x1024 a 75hz.

Revisa en la configuración de video todo lo concerniente a la aceleración 3D, GL, y fijate si tienes actualizados los drivers DirectX.

Eventualmente, también revisa que drivers de la placa de video tienes instalados. A veces suelen provocar problemas. Puedes probar instalando los que trae el CD que viene con la placa. Si esos son los que tienes instalados, entonces, prueba descargar de la página de ATI los últimos drivers actualizados e instalalos.

No, no hay forma... sigo con los problemas.
