[HELP] Emulator Exception?

[HabFree]

Hello Ragezone,
I have for a long time now this error.


13-9-2015 16:31:36: Error in thread Room [ID: 753] cycle task -- Process Floor Items:
System.FormatException: The format of the input string is incorrect.
at System.Number.ParseDouble(String value, NumberStyles options, NumberFormatInfo numfmt)
at System.Convert.ToDouble(String value)
at Skywave4.HabboHotel.Items.RoomItem.method_2() in c:\Users\Administrator\Desktop\Skywave4\Skywave4.HabboHotel.Items\RoomItem.cs:rule 763
at Skywave4.HabboHotel.Rooms.Room.method_33() in c:\Users\Administrator\Desktop\Skywave4\Skywave4.HabboHotel.Rooms\Room.cs:rule 3101


Code from RoomItem.cs rule 763:

case "wf_trg_timer":
if (this.ExtraData == "1")
{
this.ExtraData = "0";
this.UpdateState(false, true);
}
if (this.string_2.Length > 0)
{
this.method_8().method_15(this);
this.ReqUpdate(Convert.ToInt32(Convert.ToDouble(this.string_2) * 2.0));
}
break;

Code from Room.cs rule 3101:

if (this.hashtable_0 != null)
{
foreach (RoomItem class2 in this.Hashtable_0.Values)
{
if (class2.AnimatedRoomItem != null)
{
class2.AnimatedRoomItem.OnCycle();
}
if (class2.bool_1)
{
class2.method_2();
}
}
}
}

The rule in the codes with the fat fond is the row from the error.
