Putting the version in the window title, like the portable version, is the best/obvious solution.
Still no link to your website.
No link to the FAQ.
Perhaps just put FileBot into a more familiar application window with file, tools, help, etc menus? These exist for almost every bit of software, on all platforms.
File: Open File(s)... Open Folder... Exit.
Tools: Backup Formats... Edit Formats... Groovy Pad... OpenSubtitles Login... Options...
Help: Getting started, FAQ, User Forums, Check for Update... About...

No need to reinvent the wheel. It'll mean a few less forum posts asking silly questions, a few less items needed on the FAQ. If something is frequently asked, then make it easy to find (i.e in familiar place) or the function self explanatory where possible. All this makes for elegant software.
