Well first, here are the latest codes:
Basically, I think you should flash with the latest firmware and fix. Here is a guide to doing, on the Box Super:http://www.freewebs.com/boxsuper/
You say it keeps updating? Has it never even scanned a number of channels, and then you have exited out back to tv? Sometimes you have to flick it on and off a channel such as Sky Sports or Setanta, to get the code update to 'kick in', even while you think the transponders are still updating (frequencies being detected and allocated to your box)when in fact there are many transponders that do not even transmit.
Then you enter 1570 and scroll down to EMU and click right to turn it on. Then exit to tv.
Sometimes you have to flick a channel on and off or even the box itself to 'kick' the code update on a bit. Sounds crude I admit, but works for many..
I know this is a lot of info to fry your brain, but the more your play with it all, the more you'll learn and eventually you'll just flash and fix and won't have to enter your codes so often.
As for the latest codes, firmware and fixes, you can get them all on a handy toolbar here
. The codes are on the Keymaster which you can install from the toolbar 'Big Key' thingy.
Hope this helps
ps The codes are also on the BigmaQ
