"MapleStory" Getting a message saying Input/Frequency/Video Mode Not Supported? These simple instructions will help fix it!

Go to your MapleStory folder and double-click setup.exe and then click No on the pop-up
it will show up the same screen at different frequencies and tells you to click Alt + H if it works.

You might see the picture, but if you see a box showing something about frequency not correct or something similar, you just let it continue to the next frequency, and when you see the picture they show up without the input not supported box there, you can now click Alt + H or wait until the popup shows up asking if it is the correct frequency and you click yes.

It should show that the computer has been set to XX Mhz frequency...XX meaning a number
When it says restart MapleStory, it means re-open MapleStory
