为什么玩天堂2经常弹出来啊?高手请进

为什么玩天堂2经常弹出来啊?然后就显示这个:

OS: Windows 98 4.10 (Build: ***********)

CPU: GenuineIntel Unknown processor @ 2424 MHz with 255MB RAM

Video: NVIDIA GeForce FX 5200 (5664)

Insufficient Memory.

Please check the Virtual Memory Option and avilable hard drive space.

You can check them by going to : Control Panel->System->Advanced->Performance->Settings->Advanced->Virtual memory.

History: FMallocWindows::Malloc <- FMallocWindows::Realloc <- *********** 1081728 FArray <- ATerrainInfo::UpdateVertices <- ATerrainInfo::UpdateVTGroup <- ATerrainInfo::PostLoad <- ULevel::PostloadObjects <- ULevel::Load <- Load_Level <- UGameEngine::AdjustTerrain <- L2Seamless <- UGameEngine::Tick <- UpdateWorld <- MainLoop

请问这个到底是什么意思啊 ? 帮忙解决一下啦

虚拟内存手动设置大点2048M吧，还有就是多切换的话容易出现这个错误。
