Based on your very thin description of what you actually did.... I think there are several things you missed:
1) After you "fill in" the tiddler with some content, you must press the tick mark that is above the tiddler editor itself... NOT the tick "at the far right" (by which I assume you mean the circled tick mark that appears in the *sidebar*). The tick mark above the tiddler editor is the "done editing" button that stores your input into the running TiddlyWiki system that is loaded in the browser, while the circled tick mark in the sidebar is for saving all changes to the document back to your filesystem.
2) When you open a TiddlyWiki, it does *not* automatically show the tiddlers that were previously opened. Rather, it displays only the tiddlers specified in the "default tiddlers" entry of the control panel (accessed from the gear icon in the sidebar). A complete list of all the tiddlers in your document is shown in the sidebar "tabbed lists". You should find the tiddler you created there, and click it's title to open it into the StoryRiver. If you want that tiddler to appear automatically each time you load the document, then you have to add that title to the default tiddlers entry in the control panel, and then save your document to preserve that setting.
3) When you save changes to the file using Chrome, TiddlyWiki employs a generic "download saver" method, that uses the browser's built-in "download a file" handling to allow you to save a local copy. This is necessary because modern browsers no longer permit direct local file I/O activity... at least, not with a separate browser-addon like TiddlyFox (for Firefox). Thus, every time you save changes, it will "download" a copy of your document. By default, Chrome just places this file into your "Downloads" directory and, if there is already a file with that name, it adds a "(#)" suffix to differentiate. To take control over the location and name of the file that is saved, you need to change the Chrome settings:
A) choose "settings" from the Chrome menu
B) scroll down and choose "show advanced settings"
C) scroll down to find the "Downloads" section of the settings
D) check the "ask where to save each file before downloading" option
From then on, when you trigger TiddlyWiki's "save changes" button, you will get the standard "pick location and filename" save-a-file dialog. You can then navigate to the current directory, and select the name of the currently loaded TiddlyWiki document. When you press save, it will ask if you want to replace the existing file. Press OK. After the file is saved, you can reload your document (F5) to confirm that your newly entered tiddler IS present.
Hopefully, these instructions will clear up your mis-understandings, and you will be on your way to creating lots of wonderful TiddlyWiki documents!
enjoy,
