Problem upon launching

[balangayfrix]

Hi there, I'm just new in this server, and as of now I can't play yet because upon launching the heRO application the screen will turn into black. I already patched the client and I can hear the BGM, but my only concern is I can't see anything on the ragnarok window.. pls help me. for now I will try to redownload and reinstall it, then if the problem persist pls help me. i really want to play in a low rate server??
