As the title says, since upgrading to 8.1, the Skydrive app can browse files, but can't open any of them--I get a brief download box that stays at 0%, followed by an get an error message, "1 interrupt Action", Error 0x800040A41: No Error Description Available. I can still access Skydrive from Word or other programs, but I prefer having a shortcut to see all my files and open the program the file needs. What happened?
