Ok, thx for your replies.
for the warehouse map, it only crash with cpma. I've just tried to load it under e+ and it works. It's maybe related to my config. I'm moving to e+ for our dedicated server.
Just a suggestion : I've put /textures/ad_content separate from ql-textures.pk3 so i'ts easier to customize it with a server/clan infos.

well, I've no explicit error ...I've tried with both quake3.exe (client and dedicated server) and ioquake3.x86.exe / ioq3ded.x86.exe with those command line :
server : ioq3ded.x86.exe +set dedicated 1 +set com_hunkmegs 128 +set fs_game cpma +set vm_game 2 +exec server_XXXX.cfg

client : ioquake3.x86.exe +set com_hunkmegs 128 +set fs_game cpma +exec lvr.cfg +connect XX.XX.XX.XX

when I change map to warehouse, the client disconnect from the serveur without any error message (back to main menu screen). Nothing in games.log either

Good idea ! I've made several test starting cpma client and choose pratice with differents modes :

- In tournament, HM, TDM, FT modes, map loads and run fine with bots.
- In FFA, map loads if I choose no bots, and hangs if I try with some bots !

As it crash with the client, I can copy to clipboard the log. See attached file. These are some errors at the end.

On my birthday the QLPP18 was released. Who could send me its 4 new premium maps for my adapting them for original Quake III Arena?

Thank you, I'm going to adapt them as soon as possible.
