That should not happen. You should be able to resolve it with the DMV. Show them that you appeared and satisfied the requirements. The only time the court would consider suspending or revoking your license would be if you failed to appear, if you are arrested, charged and convicted for violation of Minnesota driving law.
If they tell you that you did not satisfy the requirements, then you may now be required to show financial responsibility.
You can send them an email to determine their abiliity to help you: motor.vehicles@state.mn.us
