I am transferring data from an old hard drive to a new hard drive. I "exported" all my messages, which included a lot of storage folders from the old drive to disc. Now I am trying to "import" the messages and it tells me the folders "are empty or in use by another program". They are not empty..........I can clearly see that the date transferred correctly. How do I get the storage folders and messages contained therein imported in to Windows Live Mail on my new hard drive??
