I never tried Milkshape, because I heard that until you registered you couldn't save any of your work. So, you could make a cool model in Milkshape, but if you hadn't paid, you couldn't save and all your hard work would disapear.
Is that bull? Can you keep using it after 30 days?
Also, if it stops working after 30 days, why can't you just reinstall it? Then the counter would go back up to 30, wouldn't it?
