+1 rep. The op is a huge failure
Honestly?
Let's see:
The OP posts that the update has erased all his keyboard save settings. Now that right there is a right irritation as keybindings take time. He is however branded a troll and an utterly useless forum post (as in utterly useless as it does not even begin to attempt to help the OP or get to the bottom of the problem, which is ignored entirely in favour of an OT ditty) that sings a little song brandishing the OP a troll gets rep for insulting someone else?
Interesting.
Cannot help but think that the forums would be a much better place if people actually read and start helping the OP rather than jump on the 'troll' bandwagon every time something goes wrong.
