You'll get it at 200 and 400 too. They all suck and you're better than 99% of them. You just hit a bad spell.
Sorry I have nothing more to add but you're a winning 400 player. Meh. A few nips and tucks and you'll be a slightly better winning player. Avoid sharks and only play loose 200 and 400 games but I'm yet to see a hole in your game. Play a LOT of hands before you decide you're struggling/hammering any game. The long run is very long in poker.
