I'm fairly new to modding games, I could seriously use some help with this.

I've downloaded the JaySuS Swords, the More Craftables Mod, the Uruk-hai Sword, Berserker Sword, helmet and shield (seperately), Ringwraith greatsword and a few others but they wont apear in the forge, I've managed to get them to work once but they wont work again, I'm not sure what happened, please help.

Um how advanced of a smith are you? I run Jasus swords and everytime I gain a perk/level a few more swords are availible for crafting.
Though the propper place to ask would be http://www.gamesas.com/topic/1285299-jaysus-mods-for-tes-v-skyrim/

I've maxed out my level for smithing, I've got some of the mods work once so all the more Craftables mod should show new options like Falmer armour but it doesn't.

I've tried installing then uninstalling the mods over and over but it wont work.

The default launcher has a nasty habit of randomly deactivating mods. Double check that they're active, and consider using http://www.skyrimnexus.com/downloads/file.php?id=1840or http://www.skyrimnexus.com/content/modmanager/to make sure they stay active.

I have the NMM installed and I often spam the tick-box-things for the plugins to make sure they're active but it doesn't seem to work much.

What's BASH like? Do I need anyting special to run it? Or is it an upgrade on the NMM?
