Hi

I brought a new Hard drive for my UK Series 1 Tivo and it had TyTools already installed. Problem is the version is 9r18 and I would like to upgrade it to the latest version.
I can't work out how to do this as it mentions the NowShowing file is no longer needed. I thought I would just replace the exsisting server file, but as I don't know how to stop the service it won't let me.
My other concern is, could just replacing the file with the newer software cause me problems when I restart the Tivo?
