Topic: Da vinci 1.0 l_error or software crash

A week ago my computers power supply stopped working dell warrantied it by replacing my mother board and power supply.  Now when I try to print something on my Da Vinci 1.0 after slicing and after I would press print for the last time my software shutsdown or I get this error message.

L-ERROR
System.NullReferenceException:Object reference not set ot an instance of an object.
at XYZ view.wpf.Export.Decryp(StringtoDecrypt, String Key)
at SYZ.view.wpf.Export.Offlinesendata(String offlinebuffer)
at XYZ.main.LoadGCode(Stringfile)

I see on here were someone else has got this error but it appears they haven't got any help yet either.  I am less that happy with xyz's customer support so far.  Maybe they will come through in the end they just don't seem to be in much of a hurry to help.  any suggestion?  So far I have tried multiple file that have printed in the past,  uninstalled and reinstalled my software,  tried before update and after,  used netfabb file repair (per xyz's suggestion),  and open software with admin rights.  Any more suggestions for me to try?

Have you tried uninstalling and reinstalling the USB drivers. This is not the same as the software which you said you already did. Also make sure your motherboards also known as chipset drivers are up to date since it is a new motherboard.

Printing since 2009 and still love it!

So far I have tried multiple file that have printed in the past,  uninstalled and reinstalled my software,  tried before update and after, opened software with admin rights, and used netfabb file repair (per xyz's suggestion),  downloaded software direct from xyz's site, uninstalled and reinstalled printer drivers, updated motherboard chipset, installed all possible update on the computers end, Restored computer to a date before I had this printer and reinstalled software.  I tried printer on another computer and it worked fine.
