I've had nothing but problems with Civ4 since day one. I used to just get CTD without any error messages. I tried every single fix and still nothing. I have encountered a new problem with 1.52. Here is the error messages as they appear (bad grammar included): Your system has run out of video memory. Please trying reducing your video settings. File:\main\civilization4.bak\SDKs\Gamebryo2_0\CoreLibs\NiDX9Renderer\NiDX9SourceTextureData.cpp, Line:310 Then after I click OK I get this: Microsoft Visual C++ RunTime Library RunTime Error! Program: ...raxis Games\Sid Meier's Civilization 4\Civilization4.exe This Application has requested the Runtime to terminate it in an unusual way. Please contact the application's support team for more information. Here are my system specs: Asus P5AD2-E Premium MB Intel Pentium 4 2.8 Ghz 1GB Ram ATI Radeon X600 pro 256MB Can anyone help me with this or point me in the right direction? Thanks in advance.
