Problem with urbackup client : "There was an error. Currently nothing can't be backed up"

Hello, I have a problem with severel computers with urbackup client(version 1.4.11) and I get this error : “There was an error. Currently nothing can’t be backed up”.
This is the debug log of the client :
2016-06-13 11:27:40: WARNING: Upgrading…
2016-06-13 11:27:40: ERROR: Error preparing Query [SELECT tvalue FROM misc WHERE tkey=‘db_version’]: no such table: misc
2016-06-13 11:27:43: ERROR: Error preparing Query [DROP INDEX filehashes_idx]: no such index: filehashes_idx

2016-06-13 11:27:43: ERROR: FileServ exit with error code: 99

If someone could help me I will be very thankful.

Something prevents it from binding to port 35622. Either you have another program that uses that port (unlikely) or you have a firewall which blocks it from binding to that port.

It was the firewall from my antivirus program thanks a lot man :slight_smile:
