I really love this software and I thought it was totally worth the purchase price, but at this point I cannot recommend it since the application is unusable at this point. I cannot open the application because my Mac thinks another copy is already running. I have applied the workarounds suggested in other threads and still cannot open the program. I have made sure my software is up to date. I've written a support inquiry and have gotten no response. I've gone from loving the program to feeling like I wasted my money. I have a brew day coming up and I'll have to find another way to create my recipe. I'm feeling kind of heartbroken about it, I thought I'd found a treasure and now it has been lost. :-\
