Before I open up a support case, I just want to quickly ask everyone if the same is happening to you.
When you (re-)import music folders to your collection in Traktor 3.10, i.e. check for new files in your watched folders, do any results come up? Loading the collection with 3.10 takes about the same time as with 3.9, or a bit less than usual, but when I import my music folders, new files won't show up, and no Analyse popup appears. I installed 3.10 as an update to 3.9 through Access, and I haven't tried re-installing, also no settings changed meanwhile that would warrant this.
