Hmmm... That's odd. I have an HTC too (Evo 3D) and when I got to Accounts and Sync, then tap on Google, I get the option to Delete Account.
Maybe see if this does the trick - Settings > Applications > Manage Apps > find and click on Google Play Store > Clear Data & Cache
Also, it could just be that since more than one of you is getting this error, that Google Play is being a little wonky today.
