Need help rescuing photos taken with ND4.0 filter

Here is two photos of little interest, but I need to rescue these kind of photos:

First: f5, 1/100

second: f5, 120 seconds exposure with ND4.0 neutral density filter

All settings are the same except for the use of the ND4.0 filter that requires the 120 seconds exposure.

First, I was under the impression that using a ND filter would not screw color balance that way. If someone can explain what is happenig here, it would be of great help.

Using my limited Photoshop skills, I was unable to make the colors of the second shot looks like the first one. At best, all I could manage to do is to make the whites looks more white.

Do you Photoshop wizard out there think it is possible to correct these kind of shot to be usable at all? If yes, what kind of step would it requires?
I know ND4.0 filter is pretty intense, but I want to take photos of crowded place and make it look empty. In that department, the ND4.0 filter do a great job, but the color balance is killing me.

Thanks

drake, I was shooting in raw, but the white balance setting didn't do much to remove the red tint.

scuds,

Wow, that is pretty good in so little time. My past hour of trial an error didn't bring near your results. What were the setting you changed? Levels? Curves? Did you reduce the red channel, or increase the green one?

Thanks

The result of the "auto" tools were pretty good already, just tried to make the colors more accurate, as ur original, "correct" shot!
Try it, u'll see!
