Well, I've pretty much solved this, but I still have a question...
I deleted the application from within the 'Program Files' folder, and copied its structure into a folder off the root of the drive. This seems to have stopped the DB core errors.
However, bearing in mind that I have (once again) deleted the application folder and sub-folders completely and ran the application from another location on the disk, how does LM remember my settings??
WHERE is it storing this information, and if I ever want to uninstall, WHERE do I delete it from??

Speaking as someone completely new to this, my 'fresh eyes' have a few feature requests...
1. Documentation.
2. This is a 'bare bones' application. I like this! If I wanted lots of 'show' then there are the usual suspects instead.
So, with this in mind, can I switch off ALL thumbnailing? I just don't need it.
3. Now we're down to basic indexing, is there a way to get better syncing? Cron-style? Could a service like dropbox's folder change detectionhelp?
As I said, it all seems to be working well so far. I can VPN into my home machine, then access LM through the tunnel, and my (otherwise unremarkable) PC seems to be able to cope with encryption for the tunnel AND transcoding simultaneously. Very promising!
