Hmm.... I have no idea what's causing the crash...
(bugs in IvPBot? hmm... perhaps the buggy experience code, argh!) I am unable to test it now since I don't have CS 1.6 installed on my computer, I will take a look on it anyway.
I just google this problem and found there are a lot of other people have the same problem on Windows XP (most of them have no bot installed) but have not found much solution.
You might need to take a look on:

Let me know more information when it's crash again. I think there is an option like "More info" when something crash which will give something info like this:
