You will not lose any of your Poser stuff if you update to version 4.03. Heck, you can even uninstall Poser, and the runtime folder will still exist. Of course, you're better off backing up your runtime folder. "The text editor" depends on what operating system you have. If you have Windows, you have Notepage and Wordpad. Click Start, Programs, Accessories, and go from there. You want to use a "text" editor. Don't use a program that will save the information in another format. (Example MS Word saves to "doc" format. I avoid editing CR2 files. The easiest way to handle this problem is just to resave the stuff. You might want to be very careful what you do. When you save, you'll be asked if you want to save the morph channels. Say NO. You might want to be sure you keep the original pose files as backup in case you make any errors.
