can't open itt ! =[

whenever i click the thunderms icon, my screen just goes black for like 8seconds, then goes back to normal like nothing happened.
I used WinRAR to open your file, and dragged the thunderms.exe into my maplestory folder. but it still won't let me in. Help pleasee? =[

dw, searched your Help forums. thanks anyway.

Do u hear anything when it goes black and what dose it say anything when u are in desktop mode?
