Unfortunately, if your case was dismissed for failure to provide the counseling class certificate or any other reason, you must refile the Chapter 7. You cannot reopen a case that was dismissed and not discharged. You must wait 180 days to refile and you are well past that timeframe. You cannot file bankruptcy again for 8 years from the date of discharge.
You will need to pay the filing fee again, and complete new schedules.
