Error in loading DLL (Error 48)

I have been working on a spreadsheet at work, but brought it home to make some changes (that was obviously my first mistake.....always leave work at work)! At home I am receiving a "Error in loading DLL (Error 48)" message anytime I try to run a macro. I saw a posting in the forum at the end of April '09 that was asking the same question, but it seems as if the poster's IT fixed the issue. I tried unchecking the "MISSING:Ref Edit Control" box. After I uncheck it and hit OK, excel automatically re-checks the box.

Any suggestions are greatly appreciated!

Cheers,

Not sure. Where would it be located? In the VBA or Excel?
