Antonio,

>I reinstalled Visual Studio 2003 and that seems to have fixed the problem. However, now I can't install the MM Web Forms controls on the toolbox. I followed the instructions on the help file, to no avail.

Are you getting an error when you try to install them? Did you see the information about the VS .NET bug in the MM .NET Dev Guide topic "Adding MM .NET Web Forms Controls to the VS.NET ToolBox?"

Regards,
