SLS v1.3.3 "Communication Error"

What do you want to achieve?

I’d like to launch SquareLine Studio to verify some solutions from the forum. I haven’t done it in a few weeks, my trial might have expired.

What have you tried so far?

I updated from SLS v1.3.2 to v1.3.3, and launched it.

Yes, your trial period has probably expired. We are currently working on clarifying the error messages. If you register on the website and log in to the SLS, you can continue to use the software with the free license
