Issue with Cobian Backup

Hello,

I have a problem with Cobian BackUp: it is supposed to back up one of my folders (on my laptop) to my wife's desktop. Both PCs communicate via Wifi through the Freebox. Cobian was able to make two backups, but since October, it hasn’t backed anything up (I just realized the problem!!)

Here’s what the task log indicates when I force the backup:
