I installed the new version. it still doesn't work, but I get a slightly different error this time

Ah, now I see what the problem is. You're using kinda old version of OpenElec/Kodi. There are now at least 2 new versions of OpenElec, not counting possibly new versions of LibreElec.
Would it be possible for you, to update to the newer version? As it would be probably faster, than for me to add support for older versions of Kodi. As this seems as a more of a problem with the system (OpenElec) itself, than with the Kodi version (because of the missing or old python libraries)
