Dear mailman,
First of all, I apologise if my post offended you in any way.
Now to clarify things...
First off, I have indeed read through the whole thread before posting and was aware that you had downloaded a copy of GTA3 from GameStop.
I checked with the GTA3 official website to see if it was a legitimate method of downloading GTA3 digitally and found that the links provided were all out of date apart from one, Rockstar Warehouse, which offers to ship you a copy of the PC version of GTA3.
GameStop most likely started offering the digital download version a long while after GTA3 was published in its original CD format.
Also my post was aimed at anyone in general, and not yourself in particular.
However, the reason I said "bunch of files" is because you mentioned you were not using a CD image of GTA3, and the reason I said "cracked" is because I have seen no evidence that the digital download version from GameStop is officially distributed by Rockstar Games.
GTA3 is an old game. It was first sold in a CD format and the official patch supports the original CD version.
The only legitimate digital download version I know of is the Steam version for which support will be available soon.
Of course there may be other versions which I do not know of but Rockstar's own website does not indicate that there are.
If there is indeed any sort of a legitimate version which does not require a CD, apart from the Steam version, the executable will not be patchable and you will either have to look for a crack or ask Rockstar's support for an updated version for your legal copy.
Liberty Unleashed is a public modification of Rockstar Games' Grand Theft Auto III, and adheres to all terms and conditions as well as legal disclosures set by Rockstar Games.
The members of the Liberty Unleashed Team who have bothered to help you out here, are doing so only in the greatest interest of assisting you to play Liberty Unleashed.
I am saddened that everything has to be spelled out and spoon fed in such a manner.
Now please search for a working GTA3 executable, elsewhere.
