Fatal Error CSDV18 on brics v17

Hello i need help.
This year i needed to reinstal windows amd i went from W8 to W10. After that i instaled my licensed Brics V17 and CSD 18 for BricsV17 - 64bits.
All was good till a fatal error apeared.
From that point i can't use brics and CSD on any computer. I can use brics but when in instal Csv i can't even draw a single polyline.
Do you all have any idea hoe can i resolve this?
