For the server signature errors. I think this happens when you have already another version of silkroad running like iSRO or cSRO (or whatever else). Maybe try to run your ribot and ruSRO without any windows open on your PC. Just this.
Personally, i got this error many times, but I clicked on Ok and then, Sro was still running normally, and my bot botted like averyday.
For those who their bot is targettting (i'm french, i don't know if I could say that ^^) any mobs, but not attacking, or for those who their bot is saying invalid numbers, i'm pretty sure that you have up your skill IG, but didn't changed them in the bot.
Every lvl for every skills have a different number to differenciate from each other (i think), for example, Anti devil Bow - Wave lvl 1 have the code 0XBD001, but Anti devil Bow - Wave lvl 2 have 0XBD002. So, your bot is trying to launch your lvl 1 skill but can't find the lvl 1 code cause you've already uped your skill, then an error code appear, and you get mad and go here to flood the post ^^
So, for those who have those two errors, try to put your new skill on the bot, then restart it.
Personnally, i've the error code 13. Instead of running here and flood, i try to find any solution on this post, or with my very friend google, then i'll come here if i can't find answer. Some of you should do that too, cause this post is going to be enormous if every time you have an error, you come here and cry/flood the post !
I hope i have helped some of you.
Happy botting, new year blahblahblah.
Zee.
EDIT : I've just read that :
Getting ServerSignature Error 01.
- If sro_client still launch then just ignore the error.
