Support is very Good!!!! quick response! Very good rc simulator

I have imac version 12,1 core i5 16gb ram and AMD Radeon HD 6750M 512 MB and i had error screen. I was so frustrated for that!
I have contacted support and less than 1 hour they answer and give me the solution ! When run the first time set your default language to english(if is not setting yet) them disable show tips. After that you can put your default language(other than english).
Very good rc simulator !
cheaper than windows version!!!
