CorelDRAW 2019 "stopped working error"

Hi Guys

I recently installed CDGS 2019 on my laptop (i5 - 8GB RAM - Windows 8.1) 

X6 is still installed and works 100%.

When I open 2019 and try to either import or save, it crashes.

I can drag artwork into 2019 and work on the file but I cannot import anything or save.

I have deleted all temp files on my pc.

I repaired the program from program features

I have renamed Corel Draw Graphics Suite 2019 to "Corel Draw Graphics Suite 2019 OLD"

Restarted my pc but still the same problem.

I would prefer to leave X6 on my pc as I dont have the installation disc / serial number anymore to reinstall it if 2019 fails to work. 

Hope someone can help out?
