You probably exported the animation without also exporting the reference mesh, or the other way round. Once both had been exported with the fixed tools, they lined up again.

This is not the place for general help with using Blender. Ask at the Blender Tutorial Community instead.

Official documentation is hosted on VDC:

• Blender Source Tools Help
  
• Skeletal animation
  
• Flex animation (shape keys)
  
• Compiling a model

You will see Visual C++ Runtime error R6034 when you export a DMX file from an official Blender build. This error is harmless, and will only be seen once per Blender session.

The easiest fix is deleting the VC++ 2008 Runtime libraries distributed with Blender. Browse to your Blender install directory and delete these three files:

• msvcm90.dll
  
• msvcp90.dll
  
• msvcr90.dll

If Blender stops working after you delete these files, install the VC++ 2008 Redistributable package (32-bit[www.microsoft.com]/64-bit[www.microsoft.com]).
