I have account right 2015.4,1 SE
all of a sudden on all my pc's (mix of win 8 / 10 ) I am getting an error when trying to open my company file that says:
Account rights has encountered an error and needs to close.
this error is just after loggin in to the file
It is not the PC / file as on all previous backups I get this error and on the PC I can create new companies fine and work with them.
I donloaded a trial version (2016.1) and can upgrade and open my current file correctly in read only.
any ideas on how to fix this?
