Ok!! I will tell you about my steps what i done.

1. Download the Sample.

2. Extract it into Project Folder.

3. Open MVC# 2005 Express.

4. Open Project.

5. Run (F5)

6. Error !!! It tell me "Error loading "tank". File not found.

I don't know why.

In the Content, it has the tank.fbx file.

Help me plzzzzzz.

Thanks.

That is odd, as long  as you've got 2005, sp1 for C#, and gse 2.0 the sample at http://creators.xna.com/Downloads/GameStudio2/SimpleAnimationSample.Zip should work.

Does this 2.0 sample work?
http://creators.xna.com/Downloads/GameStudio2/ChaseCameraSample.Zip

If so, maybe re-download the original from http://creators.xna.com/Downloads/GameStudio2/SimpleAnimationSample.Zip
and try it again in case something was corrupted or deferenced.  If the chase sample does not work then it could be a system configuration issue.

I can solve it now.

Don't care this topic right now.

Sorry for my stupid. ^ ^
