If you receive this message when opening the software, check that you have the most recent version installed. The latest installers are always available directly from the Toolbag page.
Check also that your firewall and antivirus are allowing inbound/outbound connections for Toolbag; manual exceptions may need to be added. The software will connect to the licensing server through “lic.marmoset.co” over HTTP with SSL.
In some cases firewall software may prevent Toolbag from connecting if it is not installed in the default location in the “Program Files” directory. If Toolbag is not installed to the default location, please re-install and try running the software again.
Still no luck? Send us an email making sure to specify your current OS and the firewall/antivirus software you are running.
