Error details: Story file location: http://www.musicwords.net/CaptivityWeb.t3
This file isn't a valid .t3 compiled game file. Possible causes:

• the original Web link you clicked to launch the game is broken
• the story file on the server is corrupted
• the file was uploaded with a compressed format such as ZIP, rather than as a plain .t3 file
• the file was garbled while being transferred across the network

You might try again, in case the problem was a random network glitch or other temporary condition. If the problem persists, you should contact the person who maintains the page where you found the launch link.
