That is a bug that shoud be sent to the developer team. Some users will feel they loose there copy of  their document: "User.tt17". Reason is when we update, we do it under the "Administrator account". Software continue to run under this account and save documents under "My documents" of admin account.

To get back our document, we should log under admin account, copy documents under proper account (proper user) and then set permission accordingly: Set owner to proper principal (user) and give full permissions to this user for those documents (if many). 

That is a major BUG that would surely affects many users. Please report to developer teams and keep me inform about it. Thanks.
