Problem about Menu Customization

I want to add a customization button on the toolbar, and did the same thing with this website:
http://www.codejock.com/support/articles/mfc/commandbars/cb_2.asp
but it crashed when I click the customization button on this line:
        CXTPCustomizeSheet cs(GetCommandBars());
and got this message:

Debug Assertion Failed!
Program:C:\test.exe
File: afxwin1.inl
Line: 418
....

I checked the example: Xtreme ToolkitPro v11.1.0\Samples\CommandBars\CustomThemes, But couldn't find what's wrong.
Thanks.

I don't think it's because I didn't add toolkit resources.
In the example: example: Xtreme ToolkitPro v11.1.0\Samples\CommandBars\CustomThemes
It also didn't #include "XTToolkitPro.rc". I tested it for link application statically and succeeded.

By the way:
when I add #include "XTToolkitPro.rc" in stdafx.h. I got the compiling error:
Compiling...
test.cpp
Automatically linking with ToolkitPro1121vc60SD.lib
e:\mylib\xtreme toolkitpro v11.2.1\source\calendar\res\resource-neutral.rc(28) : error C2143: syntax error : missing ';' before 'constant'

e:\mylib\xtreme toolkitpro v11.2.1\source\calendar\res\resource-neutral.rc(28) : fatal error C1004: unexpected end of file found

Any idea? Thanks.
