Re - Launch Issue - Incorrect Key / Cipher Issue (Security)

Hi All 

Not sure if this will be posted in the correct section, if not apologies. 

I have the No Disc req'd edition of BF1 (PC version) and downloaded and installed and launched the game fine. Started playing the campaign mode - saved my progress. Came back later to relaunch the game and got an error message displaying Incorrect Key / Cipher issue at Launch stage. 

Anyone else have this problem? If so any help as to what i can do to fix this. 

I have read elsewhere that even after uninstalling and reinstalling or repairing the game in Origin, it still does not cure the problem. Also that EA accidentally put some sort of an expiration date on their key codes?? Which i think is my problem. 

And I am posting here because on the EA help webpage you can only get to option 3 of 4 and the final drop down box explaining your issue doesn't work (Typically), so i do not know who else or where else to go to, to get my game back up and running?

Any advise or guidance would be very appreciated.

Many Thanks
