Whats wrong with my server?

[LAN@wasted]

alright, i've sent an email to Jitspoe, but have no response yet, so i thought I'd just share that problem with the community:

On some (but only some!) maps, my server will crash upon loading them.

Server crashed:
CMod_LoadBrushModel:
maps/ub_cliff.bsp has wrong version number (41 should be 38)

thats the error message, but i dont get it... wrong version number? it works fine on my own machine, but not on the server it wont !!?!!  any idea what that is and  what i could do?

Sounds like the file is corrupted.  Try reuploading it.

When did you send the email?

[LAN@wasted]

I sent the mail on Sunday night or Monday morning...

but I'm not sure if its just a corrupt file, because it happens on several maps, not just one

edit:  well, you seem to be right ... so now i have to find out what maps wont work found 4 so far
