Issue with MODs

[Amaranth]

Hello,
I am new to the SMF community, and well.. I have managed to run into a problem with a couple of the MODs. It appears that there has been a couple duplications of a couple MODs, and I can not seem to figure out how to go about removing both and downloading the MOD again to be used on my forums. The MODs I am having an issue with are the Unreplied and Donations MODs. If someone could tell me where I should be looking for the main file(s) for both these MODS so I can totally remove them from my forums so I can re-install them, I'd greatly apperciate it. Thank you very kindly!
