I use Windows 7 and WLM 2012.  All was well until yesterday when all my calendar information disappeared.  I have read some of the other threads, but not being a computer whizz, am reluctant to start "messing".  I can't see any automatic upgrades that occurred yesterday.  I still have all emails and subfolders, and Contacts.  If I log on via IE, then I get some information, but not all.

As an aside, I also have a laptop that uses Windows 10 with WLM, and there appears to be a fair bit of my missing calendar on there, although not all (same information as above on IE).

I'm not sure if it's coincidence or related, but my computer has been telling me that my C drive is almost full of memory - seems to have happened at the same time.  And bizarrely, "something" has reset my results in Freecell and changed the style of playing card!!!

I'm not one for conspiracy theories, but I did also get a message from Windows a month or so again telling me I would have to upgrade to 8 or greater and download Outlook to get further info on my computer.

Any help appreciated
