If you ever get the error “Hackshield Update Error : (0×30000030)” while you start MapleStory. You don’t have to re-download MS or anything. Just simply follow these few quick steps. I am making this because quite a few people have asked about this here and on Sleepywood.
1. Go to your maplestory folder. (Ussually Program Files –> Nexon –> MapleStory)
2. Double Click ASPLnchr.exe
3. Start MS.
If it still doesn’t work, try searching on google or somewhere else.
