Lost electrum password and seed recover doesn't work

[lliypuk2011]

Hi! I use electrum v.3.1.1 on Mac OS and generate wallet, I saved seed in encrypted file, but some time ago lost password... I thought it not horribly if I have seed, but when try recover wallet by seed I have problem, I put 12 words and button "next" gray! If I put any letter after 12 words, button work, but doesn't recover my wallet... What I do wrong?
