• The below is yopur error :

    Failed to decrypt protected XML node "DTS:Property" with error 0x8009000B "Key not valid for use in specified state.". You may not be authorized to access this information. This error occurs when there is a cryptographic error. Verify that the correct key is available.

    Clearly it is to do with the key file either not being available at the right location or the key not being registered on the machine.

    BizCrypto OpenPGP Protect Task is from teh company called ELDOS. You can look for help with this specific task there.

    your error msg also, btw, says it is in that task.
