DLCs not working

[Gottschkopf]

Hi,

I'm having problems with the dlcs. They are both in the addons folder, both are shown as active in the mainmenu/addons, but I can't start any chars from the dlcs (orcs, doomelves, doombringer, etc)

It might be a problem with UAC enabled.

I don't have UAC activated.

I'm playing on two PCs: one with normal access to internet where everything works just fine, and one behind a proxy.
I can start a character on PC 1 and play on PC 2, I can even hit "Start with the same character" after dying and it works, but I can't start DLCs from the main Menu...
