Myob ver 17 initialisation error

Hi,

 I have been using Version 17 for a long time and it has been working Ok, I am a sole trader Electrical contractor, today I came home and MYOB was not running.

Mostly my windows 10 desktop computer is never turned off except to reboot, but MYOB was running fine this morning, I use MYOB  every day,

Anyway when I came home MYOB was not running so I started it and it keeps coming up with initialisation error ???

All my business info is on there please help.

I tried rebooting and makes no difference

I have not been able to open MYOB by clicking on the MYOB icon for a few years but I can always start it by the following process..

Right click the MYOB icon and select properties

Copy  target  C:\myob17\Myob.exe

Paste this in Windows PowerShell  ( press windows and X, then press A )

Hit enter and MYOB starts

But today with no updates or changing anything it brings up the initialisation error

Please help
