Error: Too many computers have accessed this account's version of Battlefield 1

This game would be awesome to play, I can only imagine the things I could do if I didn't constantly get

"We're Sorry, an error has occured

Too many computers have accessed this account's version of Battlefield 1 recently. Please try again later."

And no, no-one has my details. I can only assume it is because I changed graphics cards today as it was working before that (albeit crashing a LOT which was related to the change of GFX card but is not related to this issue.)

Once I changed the card over it worked okay as I solved the issue another way so I put my 970 back in. Once this happened I got nothing but this terrible message.

I tried to get help from EA chat but I got told to do massively redundant things (as you can see from my attachment), for instance start Internet Explorer up for the first time to reset it to it's default status... 

And he told me to do something that needed a system reset and asked me if the chat would end.. obviously it would but I'm sure he wanted to go home at the end of the day as when I had restarted no-one was available to help via chat.

Terrible service I have to be honest. EA have a well deserved reputation where I'm sure someone could just reset the counter or something on this to allow me to play.. I'm guessing I'm gonna have to hit them up for a new CD key but if anyone has any info on how to fix this I'd rather do that.

Just so you know, I followed the steps in the chat log, attached.

I have uninstalled and reinstalled Origin (several times)

Any further info to add to this would be great. Or if EA themselves knew how to fix their own message it would be even better.
