Oh I see. Sorry! So, you're having trouble entering your Minecraft world.
Let's try to figure out what could be causing that...
Are you using vanilla minecraft 1.9 (downloaded from minecraft.net for 'windows' or 'mac')? To change your minecraft profile to 1.9 just press the New profile on your minecraft launcher, by the play button
Next, did you select play, multiplayer then direct connect and enter the ip? Don't forget to get a new ip by pressing the start server button.
Finally, make sure your minecraft username is set correctly. To do that, go to the Account (gear) tab in the middle of the learntomod homepage. Then check that your minecraft username matches what you see on your minecraft launcher Exactly - Capital letters and all! It most likely shouldn't be an email. It should match the name you see next to the Play button on your launcher. (Welcome, __ )
After you're in your world, you can press the mod button and mods should load.
A Note About Our Energy Saving Features:
After about 10 minutes of inactivity in your Minecraft world, you'll need to press the start server button again and get a new ip. But try not to stay in your server world for more than 3 hours per day, or leave it on when you're away from your computer, otherwise you may run the risk of going over your monthly 100-hr minecraft server hour limit - that time will reset each month. If you go over the limit, please contact us.
Every time you log into your world, your mod chest will be cleared - this will help prevent bugs!
If this doesn't solve it, please send a screenshot of what you see when minecraft fails to connect. To take screenshots, press f2 or fn + f2 then look in your computer's minecraft < screenshots folder.
