Even after recently purchasing 100 GB Hotmail Inbox SkyDrive Storage why am I getting mails from Hotmail telling me that I have exceeded my limit of 10240 MB, and also another mail telling me that my hotmail account is growing too fast and I should delete some mails in order to receive new mail ???

Last week my incoming mails were bouncing back to senders stating that my inbox is full. Why should I be deleting old mails in order to receive new ones when the current available inbox storage in my account is 107 GB ?????
