ok, let's write a "HOW TO TRAIN INSTA EFREEZE WITH BOTS ON SINGLE PLAYER" 
edit ur config with wordpad (or whatever u want to use) which u find in <q3 folder>/efreeze/q3config.cfg
copy and paste variables u find on the end of the post to the end of ur config. Run the game, click on MODS, select eFreeze, type /map <map name>
2nd (faster) way: in command line u can type "quake3 +set fs_game efreeze +map q3dm6" (example for dm6) and then continue with the add bots part i mentioned above ..
choose the way u like more
