URLLoader won't reload data from server a second time

I have this game that, as you start, loads the top 5 saved scores. After the player scores enough to be in the top 5, I have the URLLoader check to see if the original scores have changed. The loader appears to only keep the original loaded data, even if the data on the server changes. I also notice that the 2nd load is instantaneous, no wait time at all, letting me know it’s not even attempting to contact the server. Any ideas as to why this happens? Do I need to remove the original loader?
