Length of the data to decrypt is invalid

am getting the following error when a sub domain is receiving a shared cookie:

I have this in both web.config of each application. The 1.1 application
does not have the decryption= value because you cannot have that for 1.1 or
asp.net will error out. The source application is coded in .NET 2.0 but the
target application that's sharing the source app's cookie is a .NET 1.1 app.
