As far as I know, you can't do this the way you want.
Even though you might have created the same account NAME on both PCs, Windows does no use that NAME to grant access to the folders; instead, it uses a hidden complex character string it generated itself when you created the account.
So basically, the YOU on the old PC is a different account, with different access, then the YOU on the new PC -- and Windows will not let you copy stuff, as a result.
You could try copying the files and folders underneath Documents to see if that works.
