Cant access my nfs share after upgrade

Hi I cant access my nfs folder and delete the contens after upgrade. How can I see the folders ? so I can delete the contens
Regards Erling

NFS access and support was removed on Firmware Version 1.03.39 - (05/27/2014), and a warning message is included in the update process to advise users. For how long have you had your unit without updating?
