My HUD says "Smart Reset 2.0 has successfully reset the run-time-error scripts...".

This means that your HUD has successfully reset those specific scripts that have stopped working earlier due to script run-time errors.

If you are still experiencing weird things with your HUD, you could force reset all scripts, just in case there is some corruption.

You force reset all scripts by saying "/1.forcereset"  (assuming /1 is your command channel). The Smart Reset 2.0 and force reset features are only available on HUD v.5.00.00 and above.
