Firstly, apologizing for the crappy video, but this is where the game is for me.
To describe the video here, I had just CTD'd trying to enter the SEA1 and the video starts with me going into the MA, going to hangar and selecting an aircraft and hitting the runway. I exit, then try to enter SEA1 and it CTDs. I then re-open game and go to SEA2, no issues. I then go back into SEA1 successfully.
Now, Not shown in the video. The issue is, when I tried to use my view keys, specifically the 4 Key (Look Left) on the Numpad. It CTDs in SEA1. I also CTD once while clicking on the hangar. Not sure there is any specific reason for the CTDs while in arena, but the strangeness of having to go into a different arena before going to SEA1 seemed to be reoccurring theme.
EDIT: Should also add, I was able to stay in the arena when I could, I just refrained from using the Num Pad. I was able to navigate most clipboard screens.
I am considering another new download and reinstall today.
Also sending more .dmps your way Skuzzy.
