I will add another theory,lol
Has anyone else notice that say you have done well, but then can't hit anything and you think you have cleaned the slots out and then uninstall and reinstall the software you start doing good again?
Have noticed that in the past a few occassions myself
Just rename the install directory and change it back again but only once it generates an error. The slots all start with a fresh factor of zero which we all know increases your chances of winning by 32.89643% less whatever the troll ate.
Ssh. Don't tell anyone.
