Thank you Walt! I was able to recover my password. I’m in now. 

It would help to see the dialog where you're trying to sign in. It would also help to know where you purchased your application.
However, if it's asking for your Affinity account then you need to use your Affinity Store email and password. It would be the same email/password you would use to sign in at https://affinity.store/account
If you don't know how to sign in there, but you're sure you have an account, there's a Forgot Password link there that you can click on. Then, assuming you created the account with an email address you still have access to, you'll get an email to help you reset the password.
On the other hand, if you do not have an Affinity Store account, perhaps the sign in dialog you're dealing with has an option to say you're a new customer, which will allow you to create one.

I deleted the app and reinstalled it. That took care of the issue.
