Payment Status is in Spanish language - how do I change to English

[leofrog8]

Hi Guys, I am just creating a brand new site in 1.7.7.2 and yesterday migrated the old 1.5 site into it.  Obviously there is a lot of tweaking to do to get the old to work in the new which I am slowly working my way through.  I have a problem now for which I can't track down the reason.

Everything on the site that I can check via the BO is in English yet when I look at orders the payment status is in Spanish.  I can live with that in the BO but I checked on front page and clicked "My account - orders" and that was showing in Spanish.

I have looked everywhere - can anyone shed any light on this and how to change it please.

I also just noticed that the payment confirmation email has "Pagamento acettato" in the email subject.  This is really bad for me as it implies that my business is based in Spain - which I most certainly do not want customers to think.

Thanks in anticipation
