We were having the same issues on several internal and external computers. It is all fine now though.
Right before it happened to me it said that Method thought my computer date was Friday - however, it was not, the computer date was accurate. May have absolutely nothing to do with it
The only other weirdness was the computer said a firefox window was open (wasn't) I suspected it was an orphan Method window from Outlook - but again, still being new -I have no idea
.... but if the info helps.. there ya go :)
