compile no error，runtime error

[poplar]

I compiled osgart 2.0 rc3 with OSG3.0 and artoolkit 2.7.2.1 using vs 2008， and there was no error when compiled. My system is windows xp sp3. when I run the osgartsimple.exe, the error comes out:
"0x1026f8bc" index Referenced memory "0x4f525f32", this memory cannot be "read".

who knows how to solve this probelm, or tell me your sucessful building experence in win xp sp3(tell me the version of osgart 、osg、artoolkit). I am a student, Please help me ，otherwise I cannot go no my study.

thanks for all help
