Fallout Honest Hearts E-DE bug fix soon

Just-released Fallout: New Vegas add-on Honest Hearts has problems.
Bethesda's Xbox 360 and PC forums are awash with error reports.
More specifically, users have reported that already known issues with the main "E-DE, My Love" quest from New Vegas are preventing gamers from starting Honest Hearts.
Bethesda is aware of this and is working on "a fix", promised company poster "Nick" on the Bethblog.
However, Nick issued a warning relating to this fix that suggests some players may have to start the sprawling role-playing game over if they wish to play the DLC.
"If you already have a save game where the bug is occurring, the fix will not apply and you'll need to revert to an earlier save prior to ED-E leaving in order to play through Honest Hearts," he said.
Bethesda has also offered advice to Steam gamers who can't start Honest Hearts. The solution involves opening Steam, right-clicking on Fallout: New Vegas, selecting Properties, clicking Local Files and then Verify Integrity of Game Cache.
If that doesn't work, Bethesda suggests deleting your .ini files.
Eurogamer awarded Fallout: New Vegas - Honest Hearts 6/10. The add-on hasn't yet been released on PlayStation 3 because of PlayStation Network downtime.
