ooo such a common problem that maybe we all have done in our lifetime. well firstly you werent making a map when you opened se2k(sun edit sk) you were actually modding the game's setting itself. now what you need to do is download a map making program such as final sun(which has a shortcut to se2k in one of its menu's) so that when you open and save the setting you made in se2k, you will be saving the setting to the map and not your main ts program. now delete any rules, art.ini files in your SUN directory. And if you still cant join other games online cause it says versions incompatible, then you must reinstall ts. but before you do if I were you id make a backup file of my mod maps so that you dont lose them in your reinstallation cause it will ask you to get rid of the files installed after installation(which will be your se2k patch). So after you made a backup of your .mpr files(multiplay maps-mod maps) you reinstall ts and then copy and paste the maps you wish from your backup folder into your SUN directory. And that is that, now when ever you want to make a mod map. You must open finalsun and go from there. Remember se2k is used to modify the rules of the map that you have created, so always launch se2k from finalsun to prevent further happening of this sort. And make sure when you save the changes that it saves to finalsun. That is that and gooday.
