Can't play local mp3 files on spotify? Tracks are unavailable. Spotify tells me I can import them.

Hello,

I cannot play mp3 files from an album I just bought. Normally it should be well possible to play local files on spotify if they are on my computer. However, the tracks that aren't on spotify cloud are greyed out and can't be played. 

I have imported the local files, and spotify recognises them, as this is a new album and the songs are not yet on spotify. The songs show mp3,Windows7,PCup under 'Local files'. Then I click play. Spotify shows me the following banner:

'This song is not available. If you have the file on your computer you can import it.'

I have the right codecs on my pc, because I can play the songs just fine with vlc, however I want to listen to all my songs in the same player, and not open a different player for a different album..

Anybody seen this before?
Best regards

Glenn
