Just don't use Aeria Ignite, it's buggy and lamelamelame. You can open EE this way:
Go to the folder you saved EE in > Start the program named "_Launcher.exe"
The game will patch if neccesary and you can click the start button once it finished. o/
in addition to here above, isolate the client by copying the EE folder to an external ( or another disk space ) space. Then remove ignite. Once done, you can do two things
1) creating a shortcut to the launcher.exe in the copied folder
2) move the copied folder back to the C drive and create an another shortcut button.
By this you have a client without having ignite as background progress ( it's running on background to consume ur bandwidth, if you don't want it, please delete it )
