There's no reason that 1.48 won't work with current versions. Can you describe WHAT happens?
Can you maybe attach screen prints of your Kobo device driver settings (either Kobo Touch OR Kobo Touch Extended) depending on which you are using.
See

(As I said above you might need to look at Kobo Touch driver instead of Kobo Touch Extended).
