NFS problems with Ubuntu 10.10

Hello,

I recently installed Ubuntu 10.10 on an old PowerMac G5 (PPC) and am now trying to mount the shares I have on my ReadyNAS NV+ box. I have several shares set up, one called "media" which is set up for read only default access for NFS and another share called "Data" which is set up for disabled default access for NFS but I have enabled write and root privileges for a group called LWDG. The problem I'm having is that I can mount the "media" share but am getting an "access denied" error when I try to mount the "Data" share. On the NV+ the user "jules" has UID 1004 and group "LWDG" has GID 100. I have already changed my UID and GID for my Linux login to match the UID and GID for the NV+ account I want to use but am still getting the same error. I did a search on this forum for similar issues but have not been able to resolve my problem from the other threads. I'm very new to Linux so I would appreciate any help anyone can give me. I am using RAIDiator 4.1.8. I have added code and tried adding screenshots but can't figure out how to do this:
