Hello i have just installed Operation Flashpoint GOTY 1.91, when i started campagin mission, i get this error: Sys spec: Windows XP SP2, AMD Athlon 64 3400+, 2 x 1024mb ram, GF 7800GT 256mb, I have 3,98GB freespace on C:, and 17.5GB on F:, where the game is installed i also have over 1gb free ram memmory right now. What can i do to play the game ?

I have installed this directx_feb2007_redist, It might be good idea about downloading it in Internet Cafee, but the problem is, that i live far away from city, (more then far), i have no neighborhoods, no normal Internet connection, there are no shops and no gas or canalization, but i have great peace, clear air etc. As i sad, before it was working and it does not! I also have tried to delete files stored in My Documents in Arma folder.

Hello, i am getting an error while starting game: <table border="0" align="center" width="95%" cellpadding="0" cellspacing="0"><tr><td>Code Sample </td></tr><tr><td id="CODE">Error compiling vertex shader VSShaderPool I've installed the game, started it, everything was working correct, i've changed details on max, play a mission, then i have closed the game, and tried to start it again, then the problem occurred, I am getting Black screen for about 1 second, after i get this error. But before the same day, few minutes ago it was working very well. I have no idea what might be wrong I've tried to reinstall it, delete save folder, even delete some registry, i also have installed the latest drivers for my graphic card and DirectX Machine: 7800GT Sound Blaster Audigy 2 AMD64 Athlon 3800 2GB ram Windows XP SP2 It is The CZECH version of the game and i cannot download any update, because of my Internet connection, downloading about 100mb would took a few days from my life... And again it was working before i didn't change anything, i didn't even restart my PC.
