Problem while Syncing files

Hi, could somebody help me out? I'm having trouble with syncing files in the creative cloud. I have files that were synced just fine, but suddenly, with no modifications of my part, started showing errors with syncing.

In english: "error while syncing files" "Mc_wireframe_ajuda.xd" not synced

I've already tried everything in this article and it was of no help: Error: "Unable to sync files" to the Adobe Creative Cloud
Could somebody help me? I'm out of ideas for fixing this.
Thanks in advance
