Start the bot, then use the finger to start SRO. Now login your a/c and select the char you wanna use. Don't hit Start yet!
Now hit the windows button so you go back to desktop then run the "SROBOT Cracker" and it should work like a charm instantly. Now just hit start and you're off to bot ^_^
Note : Do not hit the bot's login button, it'll uncrack the bot ^_^
Edit : If you do it correctly, you shouldn't have any error messages.
