The IT support is outsourced and they are supposed to apply the fileset, but they forget sometimes so it's my job from now on to remind them. Frequently the census data get rejected, I assume because the filesets haven't been applied. The "Capita Chap" doesn't call in often. Thanks for the explanation though, no one seems to have a very complete picture here and if I speak to the outsourcing firm the meter is always running.
I do have a myaccount login but for some reason it doesn't always work. I know I'm putting the right credentials in because they are stored in my browser, but I only get authenticated after numerous tries and after having been locked out several times.
