Can't create new media folder.

As of recently I get a server error when I try to create a new folder in the media manager.

"Unable to load /EPiServer/cms/Stores/contentdata/ status: 500",

I already had a look at this topic without any luck http://world.episerver.com/Modules/Forum/Pages/Thread.aspx?id=85177

Looks like its trying to create a content type that already exist?

Added any new media types lately? Got guids on them all? If you changed guid on an existing type it would probably generate a similar error to that?...
