Welcome back. The same thing happened to me a few years back. It was disheartening, but I just buckled down and started earning again. Its now a routine --- get up, open my email, do the PTC, earn at least 5 cents (top coupons is worth .10), make a couple of posts, get ready for work. I don't cash out every month, I probably could if I spent more time here. But I am able to earn about $30 every other month and that is fine w/me!
Good luck!!
