Lab 1a

I just downloaded the app for Salesforce, and every time I enter in my log in information, it doesn't allow me to log-in, saying that a password might be incorrect. I can log in to the web version just fine, using the same password and log in information. I've deleted and redownloaded the app as well. and I still got the same error message. I used a gmail account and completed all the steps before 84 just fine.
