Sorry, Danni. I've never had any problems logging in. The only issue I have had with Google Analytics is when it has been linked with Craftopolis, but even that problem seems to be okay now. I set up GA so long ago now, I can't even remember how I did it!
This is a link from Etsy's Help pages that might be useful, though. It has some handy tips for setting up your account:
