Steps:
1. Logged into game and exchanged some crafting leves to Maisenta without difficulty
2. Rented a chocobo and was sent out of town, as expected, to ride the chocobo.
3. Made it to 30, 34 of the black shroud, opened my map, then closed the map and the game crashed
4. Updated my video drivers and rebooted the computer.
5. Logged in and walked towards town. I loaded the map, closed it and the game crashed at 28, 24 in the black shroud
6. Logged in again, walked to Gridania, rented another chocobo. I was able to check the map a few times before the game crashed at 24, 22 in the black shroud.
7. I ported from Gridania, as I found a thread where others were having issues with the Gridania map, and had no further issues with the game crashing outside of Gridania.
8. Returned to Gridania to try my luck. Spoke with Haurtelle in the Twin Adders and my game crashed again.

<edit> And I just logged in again and attempted to speak with Haurtelle and my game crashed after I was able to load the list of items which you can obtain with seals.
