Well guys, i dont know if this info is up to date, but still...
I am using windows 8.1 atm and had a trouble with logging into mbot.
I found a solution for myself, you must try this out too:
1) get this mbot -
[Only registered and activated users can see links. Click Here To Register...]
2) then get this patcher -
[Only registered and activated users can see links. Click Here To Register...]
3) Start mbot as administrator, insert ur sro folder
4) Execute dll injector as administrator (guide is in link above)
5) Run patcher from "2)" as administrator
6) press "patch"
7) ENJOY
##NOTE
if everything is "0", go to bot folder > config.ini and change Lang=0 to Lang=9
And yes, all files should be placed in 1 folder
