Due to changes made by KX earlier this year, the use of kdb+ now requires a license. Some details can be found from documentation by KX here: https://code.kx.com/q/learn/licensing/
I may not be able to fully assist with this as you may need to contact KX directly, but hopefully this can point you in the right direction!
