Can't play Issue 23

Am I trying to download the update too early? When I update my game I get the following error:

Error Code: 8 (DownloadFileCorruption):
Corruption detected in a downloaded file 'C:\program files (x86)\ncsoft\City of Heroes\CityOfHeroes_Main_2240.201205190417.1.0To23 00.201205220319.1.0.ncpatch'.

I am given an option to repair the file but then get the following error code:

Error Code: 58 (FileGroupApplicationErrorRollbackNotAttempted):
Errors occurred while applying the patch,
and a rollback was not attempted.
The product is likely in an inconsistent state and should be repaired or reinstalled.
The patch application errors are as follows:
Error Code: 57 (ErrorRepairingTargetFile):
File could not be repaired: C:\program files (x86)\ncsoft\City of Heroes\piggs\stage3g.pigg.

Should I manually delete the stage3g.pigg file and try to repair again?

<sigh> The launcher really leaves a lot to be desired.
I left it running while I was at work, so it could download the patch. I get home and it says ready to update. I have it update and it says ready to play.
"Oh, really?", says I. "Let's try a repair/consistency check anyway."
Launcher: "Ah, you got me! Gonna download another 94MB."
Launcher: Ready to apply update.
Launcher: Ready to play.
<load game - game crashes>
Repair AGAIN and there's yet another 226MB to download.

What is so difficult about this? It should be able to download one batch of files, apply them, then be ready to go. Why do I have to get all the way to loading the game to find out that it's just jerking me around?

So just keep trying to repair until it says there's nothing to repair and then try to load it and maybe it will work.

If it's failing repeatedly, see if you have a directory called ~PS in your CoH directory. If so, delete it and try again. Sometimes the update process leaves that directory behind and makes all subsequent operations fail. The ~PS directory should be automatically deleted during the update process.
