Can’t reinstall mods or install on a new profile mods that appear to be working in game.,

[wvjoeball01]

Spent the weekend building a brand new up to date 117 mod list.  Spent a day getting patches set up right and finally seemed like I got it. Did run up against an REFR issue but took off a dungeon bundle and got under the limit.  Played until after first dragon kill no problem then  noticed  Skyland stopped working after a vortex restart. This is not an uncommon occurance on my other computer with a 664 version of Skyrim..  i always fixed it by reinstalling.the mod but wouldn’t reinstall so I redownloaded and it worked.  That bothered me so I thought I will start a new profile and fresh install all mods now that I have everything needed.  None of the downloaded mods would reinstall with a generic red warning of unknown mod. Went back to old profile and check a mod I knew was working in the game, AFT, and it gave me the same error of unknown mod even though it’s working.  Didn’t want to play in further because i figured whatever was causing this would fatally break at some point.  Anybody have any suggestions ?
