[Vlad]

Hello.
My name is Vlad, I am a resident of Mironaft FabLab (mechatronics laboratory, Ukraine, Odesa), we have already Robodk program educational licenses (30p. permanent).
But lately we can't use them properly, because an error keeps appearing when checking the license.
What can it be related to?
A screenshot of the error is attached to the email

All licenses sold are perpetual. Perpetual licenses provide the right to use the software indefinitely, and the first year of RoboDK Software Maintenance Service is included in the initial purchase price. After the initial 12-month period, an annual fee is required to renew your Software Maintenance Service, but this is optional, and you can continue using RoboDK.

If you update RoboDK one year after your purchase but you did not renew maintenance, you will not be able to use your license. You must renew maintenance or revert to an older version of RoboDK//www.sinclairbody.com/whatsnew?Dw.

If you want to get rid of the maintenance notification when you start RoboDK you can start RoboDK using this shortcut: C:/RoboDK/RoboDK-Start-Silent.bat
