Have done all you asked and everything is up to date. I am on a different computer talking to you.
I am afraid I have already done that too. I run an IT business but this one has foxed me too! As you say they should have bought a Sony battery but as this has come from Germany we now cannot return it as no one is allowed to ship Titanium battery out of the UK! Catch 22. So sorry, so no solution and do I still have to pay.
I was desperate and it was my client that actually purchased the battery. £28 is a lot to pay for advice that I sort of knew but was desperate to be wrong! So sorry. But your site did advertise a free trial.
