I already check my game cache its not working but i fix my first bug.
For the first bug.
Here is couple of solutions I can think of:
1.Start the game as admin
2.Look if file: C:\Users\<USER>\AppData\Roaming\Mount&Blade Warband\profiles.dat exists, otherwise create it.
If you have the folder delete it (You need to know that when you delete it the characters are gonna delete to.) But after this when you create knew characters everything is ok.
