Had to revert dataDirectory to "/", but it works now!!!! Thank you Sir, you're my personal hero! I don't think, I'd ever managed to harness this Steam madness without your amazing tools. Two factor authorization, generating codes, inventory, trades, some general hints with Steam bull****... You got it all covered! Perhaps, the documentation needs a tiny *tiny* bit of love, to be 100% clear for noobs like me. Anyway, please let me know, if there's anything I could volunteer to do in order to support your AMAZING job. Also I'd like to know if you accept donations? I'd be honored to reward you for your help, when I'm done with this project.
