Spotify doesn't recognize offline playlists

[xthorr]

Hi,

I've removed the SC card, where Spotify stores the offline playlists, from my mobile phone and when I wanted to insert it again Spotify said something similar to "Your playlists can't be synchronized with more than 3 devices" and my offline playlists weren't available anymore. However, the Spotify folder on my SD card is still 17 GB big, but I have to download the playlists again. How can I make Spotify to recognize the offline data? I'm not in my native country at the moment so I'm not able to download all the GBs again.
