Hey,

I've viewed a couple of tutorials from the umbraco.tv, but one of the first examples just won't work.

I'm trying to create a new node from the video called "Creating data programmatically" (http://tv.umbraco.org/documentation/videos/for-developers/working-with-data/creating-data-programmatically) - when using the examples i get this a viewstate error: (The Viewstate error is in danish, sorry :))

[HttpException (0x80004005): ViewState blev ikke indlæst. Det kontroltræ, ViewState indlæses i, skal svare til det kontroltræ, der blev brugt til at gemme ViewState under den forrige anmodning. Hvis du f.eks. tilføjer objekter dynamisk, skal typen og placeringen af de objekter, der tilføjes under en tilbagesendelse, svare til de objekter, der blev tilføjet under den første anmodning.]
