My recommendation to everyone is to play something else. I was having the same problem with the installer, and no one seems to care about new users having issues. Every thread on these boards is filled with useless "support" for this problem. In the end it turns out that the the 1st party download is garbage and thats why it doesnt work.
Are you serious? How do the people who run this game expect to get new users? There are tons of free MMORPG's out there these days, and from the reviews Ive read - most are better than this. Not to mention, they dont put up corrupted downloads and then tell you its your fault that it doesnt work. My family in NY, NJ and NC have all been looking for a game to play together. This one wont be it.
I will be posting a review on every major site that reviews free MMORPGs, warning people that the people who support this game are generally rude and completely unhelpful and that the first party download doesnt even work. The folks who run Mabinogi might want to get their
together if they want new players.
