When trying to connect to ArcWeb Services using the ArcWeb Toolbar, the following error is returned:
"Microsoft .NET Framework
An unhandled exception has occurred in a component in your application. Click continue and application will ignore this error and attempt to continue.
Object reference not set to an instance of an object."
This error can be caused by attempting to connect to ArcWeb Services using an ESRI Global Account that had access to evaluation versions of ArcWeb Services, most likely obtained from the 2003 User Conference.
The error can also indicate that the ArcWeb Toolbar was installed without registering with ArcWeb Services.
** This issue has been resolved with ArcWeb Toolbar for ArcGIS 1.1 **
Evaluation access to ArcWeb Services, given out at the 2003 User Conference, has expired. To use ArcWeb Services in ArcGIS, uninstall ArcWeb Toolbar 1.0, reinstall ArcWeb Toolbar 1.1, and sign up for ArcWeb Services by purchasing a block of credits or getting a free evaluation trial.
