I had that error with another mod. I simply went into the mods folder and rmb clicked each modlet went to properties then removed the read only and haven't had an issue since.
Actually come to think of it I did have double up mods folders so the one in the desktop which DMT looked for then one in the game folder as well. I believe you need the mods folder in the game folder but not the mods correct as dmt then writes the mods to the game folder mods folder yes or.
