welcome to the forum
delete the two *.ini files and restart the game (it will create a new one on launch);
they are
usually located in
...\Documents\My Games\Skyrim,
but MO creates it's own (if I'm not mistaken?), so you need to find these (no idea where, sorry),
and delete them (same as above though, new ones should be created one launch)
if that
doesn't already work, upload the launcher.log please, stored in
...\Skyrim\Enderallauncher\system\log
hope that helps
