VS 2008 express edition, OWC office spreadsheet 11

Hello All
I am working from two computers, one in my campus and one in my home. I already make a short project with form and OWC spreadsheet in the userform. It works well in my campus and I want to continue in my home. After copying all directory of the project to my home computer, the project failed to load. Any Suggestion?
Thank you very much.
