Runtime Error 1004

Guys,

Urgent help required. I am getting "run-time error 1004" programmatic acess to visual basic project is not trusted.......

The error occurs while executing a layout in the planning package in EXCEL. Can some one be helpful in pointing me out in the right direction. So far I have lowered the security for running macros in excel and also enabled "Trust access to Visual Basic", but no use.

Regards
