Can't reinstall Spotify on Windows Phone 8 (Lumia 730)

[user-removed]

I was having some bugs with Spotify and the Storage information indicated it took 30 Gb (impossible), so I uninstalled Spotify this morning. 

Since then, it's been impossible to reinstall it, as I keep getting an error message, asking me to check if my phone is up to date (it is).

Attached is a screenshot (in French).

Any idea how to resolve this? I have a Premium account, but if I can no longer use it on my phone... there's just no point!
