Those 2 errors you gave are not errors, they are messages that pop up in the loading screen to tell you what stage FPSC is at compiling the map.
If it stops at "Loading Active Guns" and doesn't move from there then you know you have got some problem with the guns attached to the player start marker or a gun placed in the map. Delete a gun and it's ammo one at time until you find the gun that is causing you the problem
I'm not rly sure about "Creating Element's" though
