BSOD Windows XP, TS ver 2.9.126

[JPSeuropa]

Hi,
Just reporting what happened today. I decided I wanted to get both of my MS2 cars running on the same firmware and figured that I would upgrade to 3.4.2 while I was at it.
first car was running 3.3.1. I used your firmware upgrade tool and when it got to the end of the upgrading process...as soon as it got to done, the computer blue-screened.
The upgrade was successful however, so I finished up that one and got a sandwich.
second car was running 3.4.0. The computer blue-screened before it got to end and left me with a firmware less lump. So I tried again. This time it went like the first car. It got to the end and blue-screened, but the firmware was installed. Reloaded my tune and all was good.
I am connecting via bluetooth with your adapters.
Keep up the good work!
