Morning Laura - I had something similar a couple of months ago, car completely dead, no lights on the dashboard or anything, let alone cranking/turning over. And that was despite having a fully charged battery... In my case when I investigated it I was able to sort it by cleaning a couple of contacts in the fusebox. Start at the battery, on the live terminal there are a couple of leads coming off it, one goes to the starter motor, ignore that one, t'other goes to the engine bay fuse box on the passenger side of the engine bay, this is the one you need to work on.
VERY IMPORTANT SAFETY NOTICE - DISCONNECT THE BATTERY AT THIS POINT!
The fuse box you need is at the back passenger side corner of the engine bay, remove the cover and you'll see the end of this wire from the battery coming in to an eyelet connection and bolting onto some metal strips, remove the nut clean the eyelet and the part of the fusebox it connects to with DRY scotch-brite / steel wool / fine sandpaper before refitting them. Now follow that bar along and there are "fusable links" essentially thin metal strips, remove them and clean them the same way. Put the link back on, put the cover back on the fusebox, reconnect the battery, pray this does fix it as the tailgate window is going to go down when you reconnect the power and you'll need the power to be back on to wind it back up, and hopefully your freelander should start now.
