Do I need a viewer? You do not need to install or download anything else. You just need the JRE - "Java Runtime Environment" (which you probably already have). SailorXv3 is a java program and will run by itself. Simply download, unzip and open the file named "SailorXv3_22_1" or "SailorXv3_22_1a". (The extention depends on your operating system.)

ERROR about some javaw.exe file! Let me guess: Windows. I believe this only happens if you download the 32 bit version of SailorXv3 and then try to start it in a 64 bit Windows system or JRE.
You can try the following:

  1. Find the javaw.exe file on your computer. It should be in the same directory as java.exe.
  2. Rename it to javaw_old.exe.
  3. Make a copy of the java.exe file.
  4. Rename it to javaw.exe.

Now try running SailorXv3 again. If you ever run into java related problems after this remember to simply restore the original javaw.exe file. You should be fine though.

When I updated to a new version I lost my Senshi! Here is what you need to do:
In the data folder there is a senshiOtaku.csv file. One line per character.
Just copy and paste your characters from the old into the new senshiOtaku.csv file!
Just make sure you keep all the formatting: no extra spaces, line breaks or similar. Use the simplest text editor you have, like Notepad.
