I don't know why, but I assume it is because the server was bussy. Try again, it shuld work. I am working with it all the time.
If u like this utility try the all group
After compile them u can set Hotkey to every one of them
I use the following
[alt-R] close and reverse
[alt-S] Sell
[alt-B] Buy
[alt-C] Close open orders
[alt-z] Make proffit to Zero (After u have some proffit and u want to set the S/L at the same price of the order)
Don't forget to set the S/L and T/P in the Buy/Sell script
