Finally someone can understand my frustration! That happened to me a few times already. People keep telling me that it's because I changed the name of a folder, etc. I did NOTHING! Out of the blue it stopped working. Like you said, it's a pain to have to uninstall the account (or delete) and then install it again, and it's a waste of time, as it happens again and again after a couple days. What the ____ is going on????? I'm tired of this! Seriously, Microsoft, take care of this incident! I'm running out of patience!
