Problem joining server: map: mp_bouncer_training

[Stuffy]

Hai
So I'm trying to join server CoDJumPer.com#5 server whit map mp_bouncer_training. If there were other maps i was able to join them but whit this i get a error: file sum/name mismatch
Btw, I started playing this server today and i had problems joining it, first i got error saying mod.iwd is different from this server, somehow it resolved itself, then i could join server and started downloading maps, everytime when i got to mp_cheops.iwd file, then my downloading speed went from 300-400kb/sec to 12-13kb/sec and then crashed.
So i downloaded some maps from website and putted them into CoD4/Usermaps folder, i created new folder and named them the map name, like file mp_cheops.iwd named to mp_cheops and copyd the files to there. Same whit mp_bouncer_training and few more. So i think thats the problem but idk what to do, Little Help please ? ^^

When you downloaded the files from the website, did you put all of the 3 files in the created usermap, including the .iwd file?
If so, leave the .ff files in there, and drag the .iwd to ; CoD4 Directory>Mods>codjumperv3_1> (here)

If the .iwd file is allready in there, delete the one in the usermap folder, this could cause a conflict.

Hoped this helped.
