For those confused about what to do, I'm going to tell you what I did. Maybe it will help? ((Windows users only. If I could get Ubuntu to work I'd do it from there

))
1) Get the download in the first post. Its not up to date, but it'll do.
2) one of the posts earlier on has a link to a 698KB copy of the haven jar file. Get it, replace the haven file from the download.
EDIT: Found a link w/ the 32 and 64 bit versions.
Here!~3) Change your run.bat file (right click EDIT) to this (this is for Windows 7 32 bit)
"C:\Program Files\Java\jre6\bin\java" -Xms256m -Xmx512m -jar haven.jar moltke.seatribe.se
For Windows 64 bit (I assume this works for Vista also...?)
Change the "C:\Program Files..." to the location of Java on your comp. Or you can just wing it and change it to
"C:\Program Files (x64)\Java\jre6\bin\java" -Xms256m -Xmx512m -jar haven.jar moltke.seatribe.se
4) Test it, if it doesn't work change the run.bat to say
-ALL THAT CRAP FROM BEFORE-
pause
Look at the error, click
THIS and work from there.
TIP: If you run the .bat and you see the cmd (That black window :p ) and it just has one line of stuff and no errors and nothing is changing, it's working. Wait. If that doesn't work kill the process and do it 2 or 3 more times. Eh.
NOTE: I'm gonna go upload my folder somewhere and share it since its hard to find an updated package.
