Recently got Skyrim for PC (had it for console before) and have been playing about with different mods. Whenever I run Climates of Tamriel, the sky ends up looking like this:

Anyone know what the problem is? Afaik there shouldn't be any mod conflicts because I don't have anything else that affects the sky or weather. I know CoT apparently uses these ENB files which I've never used before, but I think I have managed to get Skyrim running with SkyRealism and it still happens. Any advice?

Which version of CoT are you using?

V3, just downloaded it yesterday from the Nexus page.

Do you happen to have a savegame from before installing it?

V3 is actually corrupt and the author has taken it down while it is fixed. V2.1 still works fine though, but uninstalling such a mod halfway through a save will probably have some bad effects.

Oh dear lol. I don't have any saves I'm worried about thankfully so it's no big deal if I have to roll back. The only save I kept from before installing it afaik is the autosave Skyrim made just before char generation.

Sorry to pass on the bad news

Since you're new to modding though, you should check out http://www.youtube.com/playlist?list=PL20E326325BADAE44 little playlist. It's only 4 videos but they should cover a lot.
You may also want to check out his http://www.youtube.com/playlist?list=PL96C073B0B8BFC01D as he covers some really nice mods and also how to install them.

Haha no worries, and thanks for the links.
