Problem with new version of URbackup sevrer

I just installed URBackup server version 1.4.10 on my backup server. Now, I frequently have a problem with the server not responding when I try to log into it. When I click on the shortcut, all it says is loading and will not finish. I end up having to restart the service to get logged in. This of course stops all backups that are in progress and they have to be started again. This is extremely inconvenient. Has anyone else had this problem? If so, how did you fix it? Thanks in advance…Mike
