I am disappointed you changed so much.

Let's make a deal If you can solve my problem and teach me what did I do wrong I will buy it but If I don't know what is the problem I won't buy it since I cannot use it.

What do you mean I don't know this program I tried to use it but didn't do much I try to still understand this program but thank you for the help.

Isn't The DWSIM and asking question here is free?

I already used it but I thougth maybe here there is somebody who can help me.
