When you say "stop my program" I truly hope you don't mean pressing the Stop button on the tool bar (next to the run continuous and pause). This stop button is basically a task kill, and doesn't finish the clean up processes like closing references, and releasing hardware references. I suspect this is your problem and you should avoid using this stop button at all costs. It is a last resort. The famous quote is, something like "Using the stop button is like crashing your car into a tree when you want to stop it, it might stop but the condition it is in afterwards will likely not be very good." or something. Make a button on your UI that stops your program and runs clean up. You can also use an event structure to capture the close window, and have that properly stop your code.
And if you have some time you should check out some free LabVIEW training.
