Zgemnma Star 2s Running OPENATV 5.2 FTP issue

Hi
as described in title, cannot get FTP to work, reports the following error
500 OOPS: vsftpd: not found: directory given in 'secure_chroot_dir':/var/share/empty

Worked on initial install of flash image, copied on ,ipk's for autobouquet, crossepg and mgcamd 1.38. rebooted and now get the error, Telnet works ok and logs in but not great on cmd line programming!! (ipk's installed and running ok)
anybody seen this or knows how to resolve ( I have reflashed from scratch again but get exactly same message after reboot)

- - - Updated - - -

incidently, I did check the path and the empty folder was there and was empty when I could ftp

I had it in dmz but have since reflashed and removed from dmz but still the same

no, just ease of setup, had issues opening ports to test connections and was going to lock down once I confirmed all was good! had hassles before opening ports on virgin hub
