To everyone with error 2001 after install of their V+ box... have you a 2nd STB as well?
If yes, then the problem is CS sending the code whilst the other STB is switched on as well, so the V+ doesn't receive it!
When you phone CS, ask for Swansea V+ support team (took me 5 diverts to get to the correct team). Switch off the other STB, yes pull the plug. Give CS the card number from the V+ box to ensure they are sending the signal to the correct box.
It will work, you then have to reboot and will know it's worked because you get "Live TV" appearing on the display of the V+ box.
Again, switch off the other STB. If you only have the V+, then apologies and good luck
