On the first screen that loads on the app, the version number is shown above the yellow button at the bottom of the screen.
What version are you using? You could even send feedback from the app ("Need Help? Contact us" link), that should bundle this information with your question.
edit : Also, are you certain you are using the correct email and password. If you log out from the web site, can you log in again with the same details?
@Wisejargon
I've investigated this, and although there has been changes to the authentication, none touched the app log ins, so if you details are correct, you should be able to log in.
As I said above, check you can log into the web site ok with the same details.
If you are logged into RHP, and don't want to logout, try logging into DailyChess.com (or vice-versa if you use DailyChess as you primary site,) so you can test this.

Please see this thread Thread 206078
Can you double check you are using the correct email address/password to login.
So log out of the web site, then log back in again. Just to make sure the credentials are as you remember them?
If you don't want to risk logging out of RHP, log in to dailychess.com - same site, just a different name, your same details will work if correct.
@Wisejargon
Please see this thread Thread 206078One more thing to check, can you log out of the Android app, and then log back in again?
This will almost certainly will solve the issue.
If you have recently logged into the web site, you will need to log in again elsewhere (see Thread 206040 )
