Nice software BUT…
Same thing as other: “key already used”
And also, I have ***purchased*** this software twice (in 2014 and 2015). I registered it, but it reverted, some times after, to “unregistered”.
I think there is a problem with softOrbit registration system. This is the only software with which I have those kind of problems.
Try it, but do not buy it: you will probably lose your money.
