Bank should start giving interest now, but won't apply to any previous time, but should start working moving forward.
The arcade scripts were filled with so many security holes and it created a lot of pain. Every client of mine got rid of it and CF was the only hold out until it finally got the axe. I can look into it again, but I'm hesitant to recommend it, plus beyond security, it just wasn't written well for busy sites like CF without some TLC into optimizing the code which I doubt Paul wants to finance. lol.
