Very weird problem with stack and tile

[Guest]

Hi, recently I had a lot of problems with I tough was my computer, until I realise today that it was S&T causing the problem.

Every time I start Stack And Tile, my computer automaticly restart without any warning, it just restart by himself.

I have try to uninstall S&T , reinstall the installer, but even when I start the installer, after a while... it just restart by himself again.

Any idea what could be the problem? Please note that this restart thing really doesn't happen ever, unless I start S&T.

I've been using the program for a lot of time and never had any problem, it's registred.

thanks
