Report a problem

No sign-up needed. If the software opens, the easier route is "Report a problem" in its top bar: the version, your recent commands and any errors are attached automatically. If it won't install or open, or you're on another machine, write it up here. Check Known issues first; if it's listed, there is a workaround.

Export a repro package from "Report a problem" in the software (or run lb feedback on the command line). It contains the version, your recent commands and any errors, and leaves out your design file by default. The web form does not accept design files, and a screenshot may reveal your design, so take a quick look before attaching one.
