LG Viewty - Games Downloads

Question

I have just got a new lg viewty - and it comes with o games - I have got a memory card and have made several attempts to download some games. I watched a tutorial on u tube which showed how to do it - but when I went to drag the game icon into the "others" file on my desktop it won't let me drop anything in it...Im desparate to get some games and am really at a loss at how to get some. Any halp would be much appreciated!! ThanksHeather
