Microsoft has been making some pretty significant changes (including mobile apps and SkyDrive for Windows.) Recently, Microsoft reduced the size of most SkyDrives from 25GB to 7GB. Chances are, you were NOWHERE near reaching capacity, but if you act now, you can keep getting the 25GB free space by manually upgrading it. (If you already had more than 4GB of data in your SkyDrive, Microsoft already upgraded you to the 25GB plan.)
