Running Win 7 32bit. Disk is NTFS format. Eraser Version

Get Following error report immediately starting task:

Sunday, 7 April 2013 3:43:27 PM Error The program does not have the required permissions to erase the unused space on disk. Run the program as an administrator and retry the operation.

Program .exe was started by Run as Admin.

Earlier versions have worked on other HDDs on this computer with this Op system.

Any suggestions??
Could be something is interfering - have you tried booting into safe mode and trying from there?
The same suggestion holds: have you exited Eraser first?
