Help in NIOS-II when using "USER COMPONENTS"

Hi,

I have been trying to create a NIOS-II processor with "User Component" in it along with the system components. I can build the system in SOPC and genereate it and it runs successfullly. When I try to open a project in NIOS-II IDE using this SOPC component, it gives me "Internal Error".

Could someone please help me out with this. I have been cracking my head over it for the past few days with no progress. If anyone is interested I can send my project files.

Thanks,

George Vince.
