Cannot show requested dialog Error on View Database Permissions

I am having issues with the database permissions on SQL Server Express. I downloaded the SQL Server 2005 Express Edition with Advanced Services SP1 and everytime I try to view database/schema permissions I get an error "Cannot show requested dialog." I have 3 different installs of Sql Express 2005 on different machines and they all throw the same error. The error happens in a couple locations but one way is going databases > select any database > Security > Schemas > Select and right click on a schema > permissions > and click view database permissions, I get the error message below. Does anyone else have this problem?

Thanks

Scott

Cannot show requested dialog.

Could not load file or assembly 'file:///c:\Program Files\Microsoft SQL Server\90\Tools\Binn\VSShell\Common7\IDE\SqlManagerUi.dll' or one of its dependencies. The system cannot find the file specified. (mscorlib)

Seems like a managment studio issue. I'm going to move this question to the Tools forum.
