The problem that Miyoo quoted was actually fixed. The only way it should cause a problem is if you have elevated your security settings for cookies/privacy - in which case you'll need to add mymmogames.net to your safe/allowed list for cookies. If you always use MyMMOGames
this isn't even necessary as the cookies will all reside in the same subdomain. If you use default privacy settings you don't need to add mymmogames to any list.
Sorry for your troubles and we'll try to work you as best as we can, but because this problem affects less than half a percent of the forum users it's safe to say it's not a bug with our site.
