我的cpu xp1800+ 寶聯geforce4MX440 64MB DDR512 當我在進行遊戲時人物都創造好了,但是一開始遊戲就當機了 有時會跑出

OS: Windows XP 5.1 (Build: 2600)
CPU: AuthenticAMD PentiumPro-class processor @ 1537 MHz with 511MB RAM
Video: NVIDIA GeForce4 MX 440 (5303)
Assertion failed: Import.PackageIndex<0 [File:UnLinker.cpp] [Line: 439]
History: ULinkerLoad::VerifyImport <- ValidateImports <- ULinkerLoad::Verify <- ULinkerLoad::ULinkerLoad <- UObject::GetPackageLinker <- UObject::StaticLoadObject <- (Engine.Texture L2ui.NWindow.normal NULL) <- UCanvas::UCanvas <- UViewport::UViewport <- UWindowsClient::NewViewport <- UGameEngine::Init <- InitEngine
