I can do that, but the problem is this. I set it, first time I go in I will get the freeze. Then when I set it to another one, the 2nd time it won't freeze anymore, and I will successfully get in. So, in order to get the neccessary logs, it may take me a while. After getting in the 2nd time I do not know when it will freeze again, before I shut down for the night to go back in again the next day. Only sure thing I know is that each day I try to play the game I have to fire it up twice, first time it will freeze, 2nd time to get in. Occassionally, I get in on first try, but it rarely happens.
To answer your first question, no I do not remember what chunk size did I use.
