Had to re install my OS and completely forgot to back up or save my beersmith recipe's. Luckily I keep a diary with all my recipe's in so i can re-install beersmith and hopefully carry on. I sent a mail to beersmith asking for my key again and they replied straight away. For the price i paid i'm now more impressed with beersmith than ever before. Most things you pay for online with an online download the support is useless or they never respond. Top marks to all at beersmith. I'd recommend this to everyone. Even though it doesn't accurately work out the costings it's still a very good value for money product.
