Maps don't autodownload to clients, motd disappeared

[BigFoot13]

Problem 1:

I just realized that for some reason my maps dont auto download to clients that connect to my server. this is a problem since I play a lot of custom maps and clients that connect cant download them. they just get a message saying "missing file "mapname.bsp, disconnecting"

Problem 2:

For some reason now my motd wont work. the motd.txt file is in my cstrike directory and has worked fine in the past, but the other day i noticed it doesnt show up in game.

Any ideas for these problems? thanks

edit: just got the motd problem fixed, but for now with the map downloading I am just playing on default css maps...

yet another edit: I set up the sv_downloadurl and uploaded all my maps to my server. this worked out fine, but now whenever I download a map from the server (with bzip2 compression) to test it, it fails a crc check "Couldn't CRC map maps/map_name.bsp, disconnecting" and it does this for every map I've tried, even after I delete the map and redownload it. any ideas?
