Eye of Newt Buyer Script - TriBot

I didnt know if its legal or no, but sorry if its illegal to post for this here!

Im using free Eye of Newt Buyer Script from TriBot, and the owner is not taking care for it anymore.
He posted the Source Code on First post for guys who knows how to compile it.

The script has a problem and I found the problem, I should update the Betty's ID and Closed/Open Door.. and the script will work perfectly.

I've tried to update them from his Source Code in First post, but it shows me 100 errors with RSTile :/
How to fix it?
Where can I find RSTile package?

Thanks
