The desktop version of our software was disconnected a few years ago when we emailed every registered user explaining its end of life.
Whilst it still has limited support we are not adding any more new features, upgrades or fix any newly discovered bugs or issues. Currently Windows 11 (2023) is the last know supported operating system for the desktop version.
In the end of life email steps were included to show how to use our synchronisation/migration tool to move from the desktop version to our online version for those that want to take this path. NOTE: Since 2022 our synchronisation tool is no longer available and an export/import method is now needed. For more details see this FAQ...
