MachineKeys in web.config and app.config "Unable to validate data"

[Rocky4Q]

I wrote a small c# winform app to migrate some user info from one DB to another. The application works jsut fine but when I use the web application now it bombs trying to read the users password with "Unable to validate data". This is from the Membership class.

In the exe's aspp.config I have the same machinekey as the web applications web.config so their shouldn't be an encryption issue. Does anyone have any suggestions?
