So the main thing is you need to use the exact email and password you signed up with! But, if you can't remember, you should still proceed to go to
www.ARTandSUCCESS.com, click "log in" in the upper right hand corner of the website, and if you've forgotten your email OR your password, you can reset it. If you saved the original email you received when you signed up, it will show you the email you used.
Also, if you've forgotten your password, you'll need to reset it as only you can do this - but it is very easy to do. Basically, you go to www.artandsuccess.com, click on the "login" in the upper right hand, put in the email above, and if you can't remember your password, you will be given the opportunity to change it -and only you are able to reset it as I have no access to your account.
As a last resort, there are a few things you can try: 1) Use a different browser than the one you are using, like Chrome or Firefox and 2) restart your computer or 3) if you are trying to access the course on your phone, use a laptop, computer or ipad!
