Hi,
i have upgrade pyload with commande upgradepyLoad, after i remove pyload and reinstall but when i type setup-pyLoad i have the error : can’t open file /home/****/.pyload/pyLoadCore.py and when i see in the folder i haven’t the file pyLoadCore.py 
sorry for my bad english
I’m having the same issue.
Apparently in the latest pyload commits, they removed the pyLoadCore.py
Hopefully a Quickbox developer will fix this soon 
I will look into their repos later this week and re-tweak the installer. Thanks for bringing this to our attention! 
I would also really appreciate that.
