soft lock hike (Grand Theft Auto 4)

Crc I called Pakki to meet. I teleported to him through the trainer, but when I had to teleport to the cafe, I got into the car and teleported forgetting Pakki, and I got an icon about the failure of the meeting from below.
Then after a while I wanted to call Pakki, but in my choice it was only possible to call cancel the meeting, I pressed cancel the meeting Niko called Pakki but Pakki did not pick up the phone, I could not call the bowling alley to play or play darts, because there were no icons. solve the problem to reach Liberty City (5)
