Unable to restore lost storage folders

Can anyone help me retrieve my “suddenly-for-no-friggin’-reason” vanished storage folders in WLM? There is a way to do it, but it is not intuitive. MS apparently does not want to make it easy. I know how to use the “import” function, but I can only import the empty file folders. The emails contained therein remain somewhere on my C drive. I had this problem a few months ago and the MS tech fixed it for me in just a few minutes. I called MS support yesterday and they told me that they no longer offer telephone support for WLM despite the fact that I purchased a year’s support plan at that time. The email file names are a mix of letters and numbers so unless you know where and what to look for, it’s impossible to find them. I uninstalled/reinstalled WLM and reestablished the sync with my primary email service so I just need to recover my storage files and saved emails. Any help out there?
