if you downloaded it with script dump, then it should have saved in the script folder in the rsbotsvn folder.
then open up the script in a txt file, then save it as whatever.java and then click enter.
reopen the txt file then save is as a whatever.class file
U NEEDED TO SAVE THESE WITH ALL THE OTHER SCRIPTS IN THE SCRIPTS FOLDER.
then go to the robotsvn folder, and open a file called compile all.bat
wait for that to finish, restart rsbot and then it should be with your other scripts
