reset password, but still getting incorrect "user name/password invalid". I've used the same user name and password for years without a problem.

There is no need to submit multiple forum topics and support tickets with the same question.
It will not speed up the response, but may add some confusion for you.

If you still can't login, that means you type incorrect username or password.
Please reset your sniper's password again and make sure you use the same username and your new password to login to the sniper.
If you are still having issues, let me know your sniper's username.
