CalcQuick arguments separator


I dont know if you are still supporting this product, but I would really appreciate your help. I'm working with CalcQuick in a project, and I'm having some trouble tryng to set a separator argument. All the functions that require more than one argument returns a "Input string was not in a correct format" message error or not return a valid value.  I guess it's something related with regional options , but I already change regional options to ENG-US, and the problem persists.

  static void Main(string[] args)
            CalcQuick calc = new CalcQuick();            
            calc["Argument1"] = "5";
            calc["Argument2"] = "3";         
            calc["Operation"] = "=SIN([Argument1])";
            calc["Operation2"] = "=SUM([Argument1], [Argument2])";
            string operation = calc["Operation"]; //This works fine
            string operation2 = calc["Operation2"]; //This give me "Input string was not in a correct format" error

Any help would be appreciate...
