Hey hey, I just purchased the script as well and it runs smoothly for me.
Have you ensured that you have enough supplies in the bank
Perhaps try restarting the bot entirely / re-downloading the client.
check that all your gear has sufficient charges.
Is your setup similar to the one in the OP ?
Try making a new saved configuration instead of loading from the previous one you have already made?
You can also click the settings button and click "toggle logger" and it will show you the error message / what is going on. That can also help.
Sorry im just spit-balling some issues that could cause it to not function properly maybe (Minimize, isolate , eliminate) :P
