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.

I found this code on a site for doing string encryption/decryption. The string will encrypt fine, but I get this error when I try to decrypt. Any idea why? I posted the code below.

Hello! I'm actually encoding an encryption / decryption program. The encryption programes takes a file path in parameter, and encrypts the contents of the file and stores that into another file.

It seems like the Protect() uses the Windows accout information to encrypt data. If I know the user name and the password, can I decrypt it on another PC? If it is not, how about the exported key? On Windows Vista, if file encryption is used, Windows suggests to back up the key. If I import the key on another PC, then can I decrypt a data protected by the Protect() method? Or it is impossible by any means?
