Error Message - Document Cannot Used Template

I recently changed my text handler from Notepad to Metapad cause I like it better. Could that be why it dissappeared from my right click menu? Anyhow, anyone know where this is in the registry. Oh yeah, I also have TWEAK UI but for some reason, in the templates, I can't create a new template there. I tried with Notepad.exe, and also with Wordpad aka Write.exe but I get an error message saying: "This document cannot be used as a document template."

I also have FRESH UI and in Fresh UI, I selected "New" context menu and added extention ".txt" (without the quotes) and it confirmed that I sucessfully added the extention but it doesn't show up in the menu, even after three reboots. This is strange because it was always there, the option to create a .txt document in the right clickNew but it just disappeared.

One more thing, as per some website, I created a folder in Windows called "ShellNew" and put a blank text file in it from Notepad and then did some registry editing in HKEY classes root/ .txt as suggested from this website and created a new string etc blah blah, where you point to the SHELLNEW folder where the text file was but this did not work either.
