I have two accounts, one in windowslive.com and live.com with skydrive storage. After not checking these accounts for a while I tried to access these accounts recently and I received messages saying both these accounts are not valid accounts. I need to access these accounts due to the fact that I have important documents stored in the skydrive. Is there any way I can reach these accounts to retrieve my files under the skydrive?

Thanking you in advance.
