After a windows update - i could not open DSM Premium anymore / product doesn`t work also- WHY? ?
i bought DSM Premium
8523019 - DesignSpark Mechanical Bundle Add-on
on the 29.11.2016. A few days before i got a complete new Windows update - and today - i could not open DSM - i put in the product key - because it was requested again - but then i got the information -that the software does not run with that key...I got Windows 10 Pro with 64 Bit.
Can you tell me - what to do now, please ?
