Having trouble opening the game

[CasselCrunk]

I havent been able to play Ragnarok Online for years and wanted to get back into it after buying a new laptop. After downloading the client and waiting for the patches to download, I get an "entry point not found error". Ive looked online and tried a few fixes but still cant seem to get the game running. I have a G17, and Im worried my pc wont be able to run it. Can anyone give some advice.
