You bought Darkmatter 1, 2 and 3? Because the bundle pack for all 3 is 90$...
On the other hand, i should mention that you should never pay for something you dont know what it is. What made you think it was a modelling program?
The thing is, the darkmatter models are very decent models and allow programmers to create their games quicker.
I hope by saying your mad, you mean at yourself. Sorry.
For next time, let me help you out..
Darkbasic/Darkbasic Pro/DarkSDK are programming languages created by TGC.
Cshop is a world editor(mostly for buildings and such), but it is possible to make outdoor stuff.
Amaballis Canvas Shop is a 3d modeller program.
