As of June 15th 2018 Maproom is using a new backend to manage updates and send out sample data. The old backend was built on Fieldbook, but on June 15th that service is being discontinued. So I'm forced to use an alternative. 

This is a breaking change, which means that if you don't update, Maproom will stop working. But you can update any time and you'll be up and running in no time. Get the update here: If you're using Maproom pro, you can keep using your existing product key.
