Looking for a few tips for Empire

Hi guys,
I just switched over to empire from PP and I'm having problems. I have played at PS and PP, I started with a $50 bankroll playing .05/.10. I play for fun mostly, I like having a hobby that I love and has cost me $50 for months of enjoyment. This weekend I played in 4 tournys and finnished 2nd, 49th, ~300 and out early in the last all with 1k+ people.

Now for the problem, I can't seem to post any wins on Empire .50/1.00 tables. I have about ~2k hands in and just seem to lose more. I switched to a very tight play(10-14% to see flop) and I'm thinking this was a mistake. I normaly play SSH style and was runing around 25-28% to see flop before I went tighter. I'm thinking more and more that tighting down has hurt more than helped me, the games I seem to find have 3-4 people calling the flop out of 10.

Would these games be considered tight? Do you think I should play a few more hands preflop? I switched over to empire from PP for the rakeback, was this a mistake? Sould I just buck it up to a bad run and keep plugging away? Should I play a little looser on tight tables and visa versa?

Thanks
