Problem With Launching Game

[rawrmuffins]

When I double click the Dragon Raja client to launch the game, the format shows up for a split-second and disappears before I can blink my eye. It won't even let me get to the log-in screen. I had previously installed the game using the first mirror on the website Dr-int.com, but it gave me an error when I tried to install it. So, I tried the second mirror on the website (suggested from GMSphinx) and at 99% it gave me an error saying "Could not install XPS.dll" or another file that has a similar name. But I downloaded the patch and extracted it to my DR folder and it actually let me play, but for a day only. I don't know what's wrong.

Have you tried running the game in Administrator mode?
