Issues With Rekordbox Cloud Sync

Im using Rekordbox with Cloud Option to keep in sync my library between my Desktop PC, My MacBook Pro (For performances), and my MacBook Air (For on the fly track preparation). And it has been working fine until now.

Yesterday i downloaded some new songs into my macbook air, added them to a playlist and then uploaded them to the cloud, and later i wanted to download those songs to the macbook pro, and i got an error message saying "Please Verify that you have the write-permission in the folder". but at the same time i can upload songs from the macbook pro to the cloud without issues.

All the devices are running Rekordbox 6.8.5

I have a gig tomorrow and this is getting me really anxious
