[Flash 8]

I am having trouble with a Flash 8 highscore sender to send a game's score to an online PHP file.

Code:

---

loadVariables("http://www.example.com/highscores.php?gametitle=Something&playerscore=3582&playername=Something&cachebuster="+random(1000000), this);

---

Something like this works fine in Flash 6, but doesn't seem to work most of the time in Flash 8.
