I can't connect to Picasa account unless I go directly from my computer where I'm already logged. Every time I enter my email and password, it says that the email is invalid. What can I do?
First, check if there isn't an extra space or character in your email address. Also, make sure that you're using only a single @ sign and you're typing @gmail.com and not @gmail, @yahoo or @yahoo.com. If you can't find the problem, try to recover your username using the Forgot your username? page. Check the official web page for further solutions.
