Haha, I apologise for the inconvenience, it depends which version of RAWR-Template you are using as to the minimum version of HFS you are required. I recommend the latest beta to help get people beta testing and reporting bugs in the newer builds. Its also convenient for me as it stops people complaining that it wont work, a new beta is usually guaranteed to work with our stuff unless a drastic change has been made to the template engine.
Also no, there is no way to update the template like that, not without manually editing, we are slowly giving options to toggle certain things but for major changes to it, make sure you take a note or do it in a way that doesn't alter the template itself. A kind of overide.
I do not know why your passwords don't work, its not really my department, it could be something to do with some options save or something, try using save to file, instead of registry.
