Dana fixed it for you this time :P
...But if you run into the problem again of downloading a .jad with no associated .jar file, her'es what to do. (EVERYTHING from getjar is like this, they only give you the .jad for download and you must extract the info locating the .jar manually. Many handsets only want to install apps OverTheAir and automatically download the .jar from the info in the .jad when the .jad is installed)
Open the .jad file with a text editor, like Notepad in Windoze, or MiniCommander on the RT.
Look for a line which starts with "MIDlet-Jar-URL: "
copy the rest of that line into the address bar of your browser (it should start with http:// or you're just missing the .jar file and fresh outta luck) and press enter (on a real computer,) or check my hub for a way to download it directly on your phone (afraid you'll have to write down the URL for that, sorry.)
This URL that you copied out of the .jad is the home of the .jar out on the web somewhere.
After you get the .jar downloaded, fix the .jad by removing all of the URL from the MIDlet-Jar-URL except the filename. Leave the space after the colon. If the app won't install, use a tool to make a new .jad file from the .jar and try again. Dana has hubs on how-to for making .jad files.
