Situation somewhat improved

I did have to resort to doing a reset on my computer, but at least it was the one where it kept my files (and this actually included a bit more in the way of settings than I had anticipated).

Even so, there has been a lot of Getting Things Back To How They Should Be - and Thunderbird as most recently downloaded looks weird and unheimlich, but after if not dangers untold, hardships unnumbered I have managed to get it to recognise my local files and getting it to incorporate two subsidiary mailboxes was a lot less hassle than last time I had to do it.

Certain other things that I thought were going to be a hassle were less than anticipated (e.g. talking to printer), but what is giving me a problem is iTunes, which keeps telling me that the Library.itl folder cannot be found, even though it is, in fact, in the default folder which is in the default location. What is this thing that this thing is, even?

Also, but probably unrelated to computer crash, in fact I think it was manifesting before that, is recent purchases loaded into Calibre saying they are have DRM and cannot be opened or viewed in Calibre. They will however open actually in the ereader.

Otherwise, a lot of the tedium is dredging up buried details.
