For those having trouble running the game I'll try to assist you as much as I can with instructions, I can try helping somewhat with getting it running but first before asking for help in this topic you need to try this guide depending on the error.
Step 1 downloading :
The easiest way to currently download the game is with google chrome it works instantly on the download site, Firefox and Opera work but they're harder to download it with due to the way that the host handles files. Internet Explorer I have not tested yet. Firefox seems to not like asking for a consent so sometimes the download fails on it. Only the latest version of Opera works with that site as well.
Step 2 Extracting the game.
LoE is compressed using 7zip you must extract the game before you run it or it will not work at all.
Winrar and 7zip should both work fine for extraction.
7-zip http://www.7-zip.org/
Winrar http://www.rarlab.com/download.htm
Once you get either one drag and dropping the LoE download to a folder with a right click should yield this menu.
The 7zip process is the same except you use the 7 zip menu tab that you can see in the screenshot.
Step 3 : Running the game for multiple versions of Windows.
Sometimes the game's login button will not work. That's because of Windows Vista and Windows 7 UAC Security. XP should work instantly. To fix this in Vista and Windows 7 right click LoE's exe and hit run as administrator that will avoid any UAC issues when the game tries to login. I can't help with Mac or Linux as my only Linux is a Debian server without a monitor connected via console to my PC and I don't have a mac.
Various error messages. :
Often you will recieve server side errors due the the sheer amount of people wanting to play right now, 508 is one of those errors. All you can do is keep trying to login at slow paces so the servers don't get even more overloaded. I haven't received enough error messages so just tell me if you receive more than 508 and I'll try and help sometimes I may be busy though so don't expect a instant response. 
Solutions to various problems. (Windows/XP/Vista/7/8) :
#1 : If you ever need to reset LoE back to default settings press the Windows logo key + r at the same time, and type appdata then browse to LocalLow then LoE then Legends of Equestria and delete the settings data. Deleting the settings data will restore LoE's default settings, you will have to re-enter your password even if it's saved for the login button to work again.
#2 Broken login button. (Vista/7/8) (Listing this twice in case someone misses it.)
If the login button does not respond exit the game and make sure you right click LoE.exe and click run as administrator I assume this is due to LoE using the Windows appdata which is protected by the UAC in newer versions of Windows. This doe s not affect WinXP. If it still does not work exit the game and start it again with run as administrator like last time.
#3 (Pending)
