I know that some people had problems accessing the new website (including me).
The problem being that many PCs, laptops and mobile devices had the old address engraved within their history and by default this would be the location they would always go to. This resulted in a '404 Page Not Found' error appearing on screen.
I have now set up a divert from the old address (http://www.hdvba.co.uk/index.htm) to the new address of https://www.hdvba.co.uk and hopefully this will automatically divert anyone having this problem.
Please let me know if anyone is still having problems or if they have now got around it.
