[Mariasol]

Good morning,

when I open a wbs17 project, a message "chilcatLog"appears that I must close to open my project
see here :

I don't know what it is.

often also when I want to close my project I can't save it: "another instance locks the program"

I am working on wbs 17 version 17.4.2
can you help me?

It looks like you have enabled 'check for updates', but your firewall blocks the connection with the server.
Tools -> Options -> General -> Check for updates

often also when I want to close my project I can't save it: "another instance locks the program"

This means that you already have opened the project in another instance of the software.
