Crash in Visual Studio when using Crystal Reports Group Editor

I have a crystal report in my Visual Studio 2008 ASP.NET project and when I select Team Expert from the Crystal Reports → Report menu, Visual Studio crashes / freezes and I need to use the Task Manager to close the program. This happens no matter how many times I try, and oddly enough, it seems to work fine on another computer with the same project.

Any help at all in the right direction would be greatly appreciated as I am pulling my hair out trying to figure this out.

I am using Visual Studio 2008 SP1, SQL Server 2005 Developer SP2, Windows Vista Enterprise SP1 and the version of Crystal Reports that comes with the Visual Studio installation.
