today I was getting every few seconds different messages - "Unfortunately, the process com.google.android.gsf.login has stopped", and "Unfortunately, the process com.google.process.gapps has stopped" and "Unfortunately, google play services has stopped". and there was no connection to my google account.

According to one suggestion I have read - I removed my google account, in order to put it again. It didn't help, and now I cannot add the account again, so cannot reach my gmail. help please!!!!
