I started making a map quite sometime ago now, and then stopped, and just recently I started it up again, and all was going well. Until, I compiled my map, it compiled fine no errors, I placed the .BSP into the correct folder, I ran DoD, went onto New Game selected my map in the list, and pressed start. Then, then load bar gets to about 1/4 of the way along then the game crashes everytime. Could this be anything to do with my map/setup?
Please any help would be greatly appreciated.

Start by posting a compile log. Then we can see if something went wrong while compiling.

One of the reasons for this would be a clip brush turned into a func_detail. Compiler says it's fine, but your map will never load.

A clip brush turned into any entity could cause this.

are all the files you map uses in the right folders? custom models... sounds... textures...

Sorry that I didn't reply sooner, I haven't been online.
But I tried creating just a simple box, which compiled perfectly like my map. Then when I tried to run it within the game, the game crashed again. Here's the compile log.

Sorry about the large post, but that's the compile report as asked.

OK sorry about this.
My map now compiles properly, then I try run it in-game and the game doesn't crash and the load bar gets upto verifying resources then stops. But the game doesn't crash.
Then if I cancel loading and go onto the console it says:
Error: Server failed to transmit the sound "Sound\C"
Any ideas?
Once again sorry about this.

Haha... Somehow I fixed it, and I don't even know what I did... oh well thanks anyways you guys. I'll post a few pictures of my map soon to see what you think. Thanks for the help.
*Hugs Everyone*
