"you do not have sufficient access privileges"

Hi there, I have 2 macs at home. One day, both macs were suddenly not able to open the files in the MBL. The error message was “The folder “Shared Music/Photos/Videos” could not be opened because you do not have sufficient access privileges.”. The thing is, the macs can see the file and detect the connection to the MBL, it just can’t open it. Any idea where the problem is? Modem? Or my macs? MBL?

Have you tried to removed the mapped shared folder and map it again?
