Hello. Admittedly, I'm playing a match instead of a campaign, is my mistake. At first, when I open the game, I get the following message: The GL_ARB_texture_env_crossbar extension doesn't appear to be available on your computer. Shadows are not available and overall graphics quality might suffer. You are advised to try installing newer drivers and/or upgrade your graphics card. Location: GameSetup.cpp:970 (InitGraphics) Call stack: 004030A1 00403144 005B958F errno = 0 (No error reported here) OS error = 2 (El sistema no puede hallar el archivo especificado.) And when you load the game 100% this another message appears: Much to our regret we must report the program has encountered an error. Please let us know at http://trac.wildfiregames.com/ and attach the crashlog.txt and crashlog.dmp files. Details: unhandled exception (Access violation writing 0x00000114) Location: unknown:0 (?) Call stack: (error while dumping stack: No stack frames found) errno = 0 (No error reported here) OS error = 2 (El sistema no puede hallar el archivo especificado.) What does it mean? Greetings.
