Hi Yuri,
I'll send you a more detailed reply privately, but essentially Maximizer CRM 11 Entrepreneur edition is not compatible with Windows 10 and CRM 12 Entrepreneur was the last version and is also not compatible with Windows 10.
You'll need to either upgrade to the Group edition (running on a Windows Server operating system) or move your Address Book into the Maximizer CRM Live shared cloud environment - I'll email further details and budgetary costs to you now.
Feel free to call me on Tel: +00(0)345-2608801 during UK office hours for a chat should you have any further questions.
