Be careful if u are using 10.10.3 Yosemity

The program is quite useful and easy to operate. I like it, and I used also the version 1.0 and now 2.0. I used it till yestarday.
The most important issue is if you updated your Yosemite to the version 10.10.3 the program is not working properly. Generally is not working at all. All you get is the whole white screen. I already send the information to the support but still didn’t get any answer how to solve it.
