All substantial mods must be put on the Data folder in the Skyrim folder, and more technical additions such as Script Extenders should go in the same place as the TESV.exe.You can start the SKSE by using the skse_loader provided,and never use any of the vanilla launchers.

I am unsure of what is causing the issue with the mod manager, if the problem is with the download, it either is a problem withvyour connection or a problem with the Nexus serves, which is rather common.

You can still install it manually,just look at the folder you got when you downloaded it, and see the readme/installation guide to see the instructions for installing without a manager.Most mods come with a Data folder in their package; what is in the data folder must go to the Data folder of the Skyrim folder, overwritting when necessary.All Esp, Esm, and BSA files must go in the data folder as well.If your mod came with a ESP or a ESM file, put it on the data folder and go to the vanilla Skyrim launcher, and click "Data Files".Check your esps and esms here and activate them.
