Alright thank you. I've gotten the LGMServer v1.7.4 from the platform page, now what do I do with it?

Alright, so this is the first time i've ever dealt with setting up a server, and it's been one brick wall after the next. My friend and I are trying to play Lapito's Galacticraft modpack (not Tekkit) through Hamachi. We've set up the Hamachi server correctly and can connect with one another through that. I've dl the Minecraft_Server.exe file from minecraft.net and ran that; everything set up properly, and I've edited the server properties so it will work through Hamachi. My friend and I can connect to the server, but get the outdated client message and cannot enter. I assume this is because Galacticraft runs 1.5.1., while the Minecraft_Server.exe, being from the MC website, is supposed to be used for Vanilla, which is 1.5.2. Just wanting to know whether i've guessed right and how to fix it. And, if i've guessed wrong, what you may think the problem is. Regards, the9thEmpyrean
