Try placing all of your TES5 files (including the .exe) in the same folder as your Skyrim game. It will look like this - C:Program Files/Games/The Elder Scrolls Skyrim or where ever you have it. It would be in the same folder that has your Skyrim.exe, Data Folder, etc. After running TES5 you will see your current esm's including DLC, but you will still get the non-existant messages. I think those messages only show for people who used TES5 before so there must be a cache folder or something we can delete to get rid of those error messages, but as for only the Skyrim and Update esm showing up putting all of the TES5 files in your game folder should fix that and allow to clean your masters. EDIT Backup all of the following files before trying (There are only like 5 small ones) I found out where to go to get rid of the error messages. First you have to activate Hidden Folders Here's how to display hidden files and folders. Open Folder Options by clicking the Start button http://res2.windows.microsoft.com/resbox/en/windows%207/main/4f6cbd09-148c-4dd8-b1f2-48f232a2fd33_818.jpg, clicking Control Panel, clicking Appearance and Personalization, and then clicking Folder Options. Click the View tab. Under Advanced settings, click Show hidden files, folders, and drives, and then click OK Now you have to Go into C:Users/App Data/Local/Skyrim and open one of the .txt files (Plugins I think?) Delete all of the plugins listed that appear on the error list. DO NOT DELETE the .txt file itself though.
