Its been a while, so I may be rusty. Try this first, it can merge, convert mods etc. http://skyrim.nexusmods.com/downloads/file.php?id=1840 If that doesn't work. Do any of those not already have an esm file? If so pick that one and convert it, the larger the better. The esp confusion is the reason I abandoned modding my fallout projects I had in the works, a large quest/companion mod, when they nerfed/broke esp's. However Esm's seem more reliable now, so I would turn the biggest of those mods that doesn't already have an esm into an esm, and see if that fixes the problem. New Modders should note that working with ESM's seems the only way forward if you make a fair sized mod, put as much content into it as you can, otherwise people will be forced to choose between your work and others. Hopefully esp's will get some more love one of these days, we'll see :) Another utility to convert: http://skyrim.nexusmods.com/downloads/file.php?id=5064 Note I make no guarantee it'll all convert right to an ESM, but things seem smoother these days. Also you might even be able to turn one that has an esm already into a second esm, you weren't able to do this in previous games, so that is on you for testing/re-search
