Try using the XNA install in the dependancies subfolder in your magicka folder to Repair your XNA framework.To be honest - I do wish the Magicka devs would really fix that XNA install issue. It really is annoying to have to deal with it every time I launch Magicka.
Back on topic though: any rough release dates for the vietnam stuff?
Will it be a paid dlc and any rough price?
What was that little patch that went off yesterday?
