GTA IV asks me for serial and unlock code !!!!!

[iGOOGLE]

I have the original game of GTA IV DVD and just installed it under Windows XP SP3.

I'm wondering why it asks me for serial and unlock code ???????

How to get them ???? I paid 18$ for this game please

The serial number is on the back of the instruction manual. The booklet that says "On Liberty" with the statue of liberty on the front.

I have a similiar issue, but I have actually misplaced the booklet with the serial on it.

I had it installed on my computer, and then decided to uninstall and reinstall to fix some problems I had, before I discovered I had lost the serial?

Contacted RockStar and they said they cannot replace lost keys, what is my next option?

I paid $80 for this...

This is another reason I stick with console gaming. If you have the game it works all the time, no problems.
