Question about Outlook Express

I'm running w's 7 and am very confused by the WLM storage folder hierarchy (used to be found in C:UsersUser NameApp DataLocalMSWLM - now my App Data folder is gone in W's Explorer, even if I enable "show hidden files and folders")

But when I use search, that file path does appear, as do the WLM folders!?

The reason I want to access and understand the hierarchy of these folders is that periodically emails I've saved in some custom folders I've created w/in the WLM app (client?) suddenly go missing. (When I attempt to read those saved emails I get a "Message cannot be found" error.) So I have tried many times, to restore those missing emails by 1) importing the storage folder into the WLM app (which also gets very confusing to view in the app, due to folder duplications etc - see below)

or 2) copying them from the folders listed below into the custom folders I've created in the app

I use POP3 to access mail from my server and WLM scatters any saved emails in the WLM "Storage" folder and 4 sub-folders that are labeled "Imported" including  some with "Fo 359" and "e1f" appended. Also sub-folders: Deleted/Sent/Drafts

Emails are also stored in 2 folders labeled with my server's name: Wavecable" with (f6) and (a4b) appended, then in sub-folders like: Save/Deleted/Drafts/In box/Sent/Junk. Not all these sub-folders appear in the main folders, which adds to the confusion.

I find this whole system to be quite unnecessarily convoluted and impossibly difficult to understand, let alone explain!

I've tried ALL the suggested fixes for this problem, including repairing WLM

It's also very annoying that when you export messages (to back them up) they are exported in a proprietary file format that can only be opened in WLM, so are useless if one wants to access them via another email program. Good grief what a pain all this is!

I have formatted windows home premium due to some problems of frequent shuuting down of PC. but now after installation and activation  I have installed Microsoft Essentials as before, but now I have problem of updating, and the error code is 80072F76. The "Try Again" never works. The "Microsoft FIX IT" also not solving. I am not a computer wizard, and so I am looking for simle solutions.

Thank you.

Program opens, conversation list is displayed but Emails are not displayed and won't open "A problem occurred while trying to open this message" is the error I get. I ran the repair for Windows essentials and it did not work. Didn't help. Windows essentials won't connect to the internet (that's the error I get when I run the repair) yet I am online with other programs easily.

Rebooted a few times and tried the repair a number of times and all things are the same. An easy solution would be appreciated.

I recently used Movie Maker to edit a video taken on an iPhone that was upside down. I was able to flip the picture so it was right side up, but when I went to save the project in a format such as MP4 and WMV, there is no picture and only the audio.  I believe I'm running on Windows 8 (the Windows 10 upgrade did not go well)  Please help!
