I'm having the same problem.
I found the hex value "3F" and I modified it to "FF" but I had the same amount of money.
124,579$.
The only thing that had changed was that the vehicle transport had to be done all over again and for some reasson I had changed figure!
I changed "3F" to "FF" and "38" to "FF".
But no changes were made on the amount of money!
Is there something I'm doing wrong?
Please tell...
yes! there is something your doing wrong... I said search for the HEX Address 0000003F... address!!! not value! you don't have to search the value.. you have to change the value to FF at the address 0000003F
Try again, Good Luck!
