Compressing map help

Hello, I successfully compressed gm_construct_flatgrass_v5 and have uploaded it to my maps folder. But when I attempt to change the map it says it doesn’t exist? Is this because of the bz2 extension or some other problem?

CModelLoader::Map_IsValid: No such map maps/gm_construct_flatgrass_v5.bsp

-snip- sorry don’t know how to help.

Just realised the problem myself all fixed :stuck_out_tongue:
