When using the latest version of NMM for Skyrim mods, I uninstalled a bunch of old versions of mods and installed the latest, up-to-date ones.
In most cases, this worked fine (a few examples: Enhanced Blood Textures, Smelters for Riften and Solitude, Gildergreen Regrown, Point The Way).
With exceptionally large mods, though (I tried only Static Mesh Improvement Mod and aMidianBorn Book of Silence - Armors before I gave up), I have problems.
The mod downloads just fine, but when I try to activate/install it so that it actually works in my game, NMM's mod activation queue lists its Status as Running and its Operation as Install for anywhere between a few seconds to a few minutes before the Status changes to "A problem occurred."
I'm wary of trying out new mods or uninstalling old ones in fear that I'll never be able to get them back.
I tried NMM's Settings, Download Options, Fix It! solution, but it didn't help at all. I have Windows 7 and fairly good PC specs.
Any workaround or solution would be great, and I can give more details if needed. Thanks!
