Can't play tr_walkway_r2 for some reason

[EtherBunny]

When I try to, I get this message popping up in my consol window:

SoundEmitter: adding map sound overrides from maps\tr_walkway_rc2_level_sounds.txt [2 total, 2 replacements, 0 duplicated replacements]
Warning: Table modelprecache is full, can't add sprites/lgtning.vmt
exec: couldn't exec listenserver.cfg
exec: couldn't exec tr_walkway_rc2.cfg

Host_Error: CVEngineServer:recacheModel: 'sprites/lgtning.vmt' overflow, too many models


What does it mean, and how do I fix it? Any help would be greatly appreciated.

If you actually searched for the thread, you'd know that the mann-conomy update broke the map. - Too many props and such. They are working on a fix, you just have to be patient.

r1 works though if you NEED to shoot some bots.
