Using your script, localhost as allowed ip in conf. Running from command line. Still get that http error 
I PM'ed him, used TeamViewer to diagnose the problem. Turned out he had two copies of the script, and was running an old copy while editing the new copy. Running the new copy showed straight away that his wallet was encrypted and locked.
I modified the script so it prompts for a passphrase, but my Windows skills are weak, and apparently it didn't work. So I guess he either ended up unlocking his wallet manually or hardcoding the passphrase into the script.
The last I heard from him:
"[11:31:16 PM] made a whole bitcoin tonight!!"
I made a few other changes to the script. like adding the option to set constant starting and stopping bet sizes, rather than using a percentage of your balance, and stopping if a certain file exists.
