TFT error.

So, I've been playing some dota, kodo tag, and TDs. Well, I've been getting this error a lot:
This application has encounterd a critical error:

FATAL ERROR!

Program c:\program files\warcraft iii\war3.exe
Exception: 0xC00000005 (ACCESS_VIOLATION) at 001B:6F08DD69

The instruction at '0x6F08DD69' referenced memory at '0x00000005'.
The memory could not be 'written'.

Press OK to terminate the application.

Does anyone know what could be causing this?
