Have you tried contacting the company?

I saw there was an email listed in the contacts page, it is info@dialsolutions.co.uk. You could maybe try and email the company to see if they have the original program. There is also a phone number, but I believe it is a UK number and I am in the US, so it would cost me to call it. I will keep looking for it, but your best bet would be an email since the company made their last confirmation statement in February of this year, meaning they are still in service.
