[Smesta]

Hi

I'm having trouble with Windows Update.
I'm trying to install the language pack and Windows 7 Test Update form there, but i keep getting this error message.

Code 800F081F Windows encountered an Unknown error

Have anyone else got that error?

I am currently using Microsoft Windows 7 RC Build 7100

Hoping for a little help from you guys
