Forum:Modded weapons in DLC3 disappear!

I completed the borderlands game a few days ago, and after that i started to mod weapons with willowtree. Everything as gone great, no problem at all, and i had around 15 modded weapons on my backpack. As i completed the game, i get the DLC3, the secret armory one, and its the first one i have. In the binaries folder, i open another folder, "DLCsetup", and i click on the dlcsetup.exe, and nothing happens. So, i put all the files of the DLC folder into my Borderlands folder. I start the game, i have the t-bone junction place and all that, but all my weapons of my inventory disappear, with the exception of one twisted scattergun, which was one of the first weapons that i modded. I buy some weapons, and i mod them again, but everytime i start the game only that twisted scattergun appears. The shield, class mod and grenade mods are there, but not the weapons. I uninstall the game and i install it again, without the mod, and only the scattergun again. But i mod some more weapons, and they appear, with no problem whatsoever. I put the DLC files into the game folder again, and they gone missing again. I forgot, the only weapon left was that twisted shotgun and a eridian cannon, not modded.
