Is this hack VAC bannable?:
As far as I am aware it is not as  Payday is a co-op game and not PvP so therefore Steam are not heavily worried about hacking.

Why is my game corrupt?:
99% of the time it will be because of your IPHLAPI.dll file being corrupt, therefore go to this link and swap out the file -

How do I know if I need the 32bit or 64bit version of WinRAR?:
If you have less than 4GB of RAM go with the 32bit, if you have more than 4GB of RAM go with the 64bit.

Should I backup my game beforehand?:
I would advise because I am not willing to take any responsibility of broken games as I have advised you and showed you how to back up your game so don't blame me if anything goes wrong and you haven't got a backup.

When I edit my money, skills and level it won't save?:
Sometimes this happens but it's rare, just go into a single-player game and quit, and 99% it will save.

How do I take out some features I don't like?:
Everything you can edit will be in the config file, don't ask me to find what you want to edit for you, you will be just as quick as me, but I can offer help in telling you how to edit the value you want.
