Every time I go to fileplanet from Planet Elder Scrolls, I get an error about security settings or being under the age of 18.

The mods I want are http://planetelderscrolls.gamespy.com/View.php?view=Mods.Detail&id=7062&id=5379 and http://planetelderscrolls.gamespy.com/View.php?view=Mods.Detail&id=7062&id=5168. Neither of these contain advlt content, and even if they did, I'm 20 years old, and I've never made an account on any site in which I've lied about my age, so I shouldn't be getting the "under 18" error.

I haven't changed any security settings recently either, and I've been able to download mods just fine for years. I downloaded Oblivion-Style Spellcasting last night, without a problem (although when I tried to download it a day before, I was getting more problems with File Planet; the page would load without any error, but there would be no download link).

I tried downloading a random Oblivion mod and tried using Internet Explorer instead of FireFox, and I got the same exact thing. is this a problem on my end, or are others experiencing this as well?

Dude, this exacly happened to me a few weeks ago. Since then I havent been able to download any morrowind or oblivion mod from the site. They servers are completely gone.

Fileplanet are having problems at the moment. They are trying to sort it.

Nothing more to be said.
