getAdminHash after loading MX 7 updater

[CF_contractor]

After updating the MX 7 01 updater on our production server, we are getting the
following message:
The selected method getAdminHash was not found.
Either there are no methods with the specified method name and argument types,
or the method getAdminHash is overloaded with arguments types that ColdFusion
can't decipher reliably. If this is a Java object and you verified that the
method exists, you may need to use the javacast function to reduce ambiguity.

The error occurred in Application.cfm: line 128

-1 : Unable to display error's location in a CFML template.

Has anyone seen this and have any idea how to fix it. We are locked out of
the administrator until I figure out what is going on?

Is this standalone or multi-server installation of ColdFusion? Did you uograde from CF7 to CF7.0.1?

Standalone install and this was an upgrade from 7 to 7.0.1
