Exception thrown in B40 when running Optimization [Solved]

I installed the new build and ran optomization on compiled strategy. I Got many instances of the Error below.
To try it. just create an empty strategy with a parameter and run Optimization on it.

System.FormatException: Input string was not in a correct format.

here is a sample coder to try:

CODE:
using WealthLab.Backtest;
using System;
using WealthLab.Core;
using WealthLab.Data;
using WealthLab.Indicators;
using System.Collections.Generic;

namespace WealthScript1 
{
    public class MyStrategy : UserStrategyBase
    {
      readonly Parameter interval;

      public MyStrategy()
      {

         AddParameter("Interval", ParameterType.Double, 60, 10, 250, 1);
         interval = Parameters[0];

      }
        //create indicators and other objects here, this is executed prior to the main trading loop
        public override void Initialize(BarHistory bars)
        {
        }

        //execute the strategy rules here, this is executed once for each bar in the backtest history
        public override void Execute(BarHistory bars, int idx)
        {
            if (!HasOpenPosition(bars, PositionType.Long))
            {
                //code your buy conditions here
            }
            else
            {
                //code your sell conditions here
            }
        }

        //declare private variables below

    }
}

Yup, there was an attempt to fix another innocuous bug .. and it backfired. We'll do another build ASAP.
