Acronis True Image 2015: Backup Fails with 0x00040014 network drive backup how to change password ?(日本語)

Someone, please tell me how to resolve.

At backup the shared folder of the company's network drive, I have changed the network password.
Then, backup was an error.
In addition, all of the tasks I can no longer run with the same error.
It is not repaired when you create a new task. (It does not ask for user name, password)
