Here, check out this guide to get you started. http://flyforhero.ucoz.com/forum/25-1140-1
The first post in the above topic should contain the links for downloading the game in separate parts. The main download is not working at the moment, so you have to download them in parts. As well, some people have trouble with the first part of the installer (i.e. they don't get all of it) and when extracting the files, an error occurs. You should try downloading it a few times to ensure that you get the WHOLE package.
With regards to class change, you no longer have to go through the tedious quest process to attain your Blade class. Simply level your character to level 60 and do the following:
-log out of the game
-access the Control Panel on the main website here:
http://flyforhero.net/
-you will see an option associated with "Class Change"
-select "Blade"
-log back into the game and your Mercenary should now be a Blade
You will begin the game in the city of Flarine. Here you will find the majority of NPCs who will sell you the things you need. It's best for you to see for yourself what the game offers. I suggest that you search and read through the forums to get a better understanding of game mechanics and the rules of this private server. We are not an "official" server, so expect quite a few differences.
As always, it's also a good idea to check out FlyFF Wiki. While this site provides information on the "official" game, it does a good job of explaining the various job classes, items, weapons, armors, monsters, etc. (essentially, the features of the game that have not been altered drastically).
