GTA 3 no cd crack

[Snuffed]

Thanks for you reply Optimummind

Here is where I am at.

Made a back up copy of both disks using cd Mate with safe disk settings.

Down loaded V1.1 patch from Take2games.

However when I try to install the myth patch I get this error
using WinRar 2.80

! C:\WINDOWS\Desktop\Myth\GTA311.ACE: Unknown method in gta3.exe
! Cannot execute "C:\WINDOWS\TEMP\Rar$EX0v.936\gta3.exe"

When trying a number of the patches I have gotten the same error from WinRar.
Unknown method in gta3.exe

Do you or anybody else know what could be causing this ?

Thanx in advance.
