Problems after updating NitoTV

Fresh JB on 5.3, installed flash 2.4 all is well, xbmc/rowmote etc install ok but after updating nito TV I get the “apt-get -f install” message anytime I try install anything else… I have re JB and narrowed it down to upgrade/updating of nito as if I update it before installing anything I get the error on doing so, so for now I have just installed things without updating it. Just wondered if anyone knows why? And is there a work around?
