Dear Microsoft

I am using skydrive on Surface RT and I have a syncing error with office 2013. Just 4 days ago, I noticed that every time I saved my document, the ribbon bar no longer says uploading to skydrive but rather says word is now saving document. Office also requires me to sign in every single time I open a skydrive document. I thought my account was hacked to I changed my Microsoft account password. Because of this error, my documents are no longer synced with my home desktop computer. Please help me find a solution to this. It was perfectly fine before 4 days ago.
