If the worms were escaping, it means the conditions in the bin weren't right. Could have been to wet, dry or acidic.
I also started off with a worm factory 360, and just like you had the exact same problem. There came a point were I almost tossed it all out. But after some reading and messing around, my worm population has bounced back, and no longer have worms escaping.
My bedding: shredded fall leaves, and cardboard, I like using the paper towel and TP rolls. I also throw in some peat. No exacted ratio, but I use more leaves since there free. Soak the bedding in some water for awhile till everything is wet. Squeeze out excess water.
Feeding: I use fruit and vegetable scrapes, that I keep stored in the freezer. When ready, thaw out, put in blender, spread out on a paper towel. Flip it over so food side down in bin. Cover with some more bedding.
I also give them chow mix from time to time, just sprinkle across the top.
Chow mix: corn meal, oatmeal, eggshells. in a 2:2:1 ratio
Just stick with it you will figure it out, and keep reading. This guy has a lot of good info
