I "smart reset" but still keep getting "script run-time errors"

If you have tried "/1.quickreset" (v5.2.1 onwards) and "/1.forcereset" (v5.0 onwards) and you're still getting the message, it means SL has borked your HUD really badly and you need to get your HUD replaced.

HUD v4.x users: recent SL changes might cause Smart Reset 1.0 not to work properly. Fix: update to the latest v5. series.
