Diagnosing ERROR (with no numbers) in Windows

This page is for the overflow of errors which don't state an error number in them (ie 131, 132 or 134). These errors are generally easily fixed.

Not enough storage is available to process this command
This type of error is generally occurs while flying, and the game engine attempts to load too many maps and uses too much RAM and hits the 2GB limit for 32 bit applications (like WoW). This application has encountered a critical error: Not enough storage is available to process this command. Program: F:\World of Warcraft\WoW.exe File: .\MapMem.cpp Line: 558 Requested 2123627 bytes of memory

If you're using any addons or custom scripts/[Config.wtf] entries, those may boost the game beyond its 2 GB limit. Try removing all addons and delete the config.wtf file first. There is an alternative renderer available that makes the game use less memory at higher settings. It's only available for an updated Windows Vista with DirectX 11 installed or Windows 7 alongside a DirectX 10 or higher card. The only way to access World of Warcraft's DirectX 11 mode is to make a change to a specific CVar.

Navigate to your WTF folder (World of Warcraft/WTF), and open Config.wtf with Notepad. Find SET gxapi "d3d9" and change it to SET gxapi "d3d11"
