Rather than get annoyed because no one has answered, as it is Christmas and some people find that family comes first, Google is often a good starting point. Likewise using the search function on these forums has turned up a feast of relevant information, namely the first: Reinstall your update. Generally when one or more of your internal settings FC the usual culprit is a bad install. Especially as you started by saying recently updated. If you can, download fastsum for windows and you can confirm the md5sum of all downloads before you install to ensure that they are all correct and will work when flashed.

Merry Christmas.
