"Spawn point is not clear", "Got a velocity too low on Z"

I'm in the early stages of making a map, and whenever I try to run the map, I get these errors and spawn in the middle of nowhere. I've moved the info_player_teamspawns all over the place, far above the ground, away from objects, etc. but it still won't work. What's wrong?

 

32 teamspawns, all of them are 64 units above the ground and at the least maybe 48-64 units away from any other walls or objects. I tried deleting all but one but the same thing still happened.

 

it should have coordinates for the spawnpoint.

go to those points, and see what's up.

 

Here it is (only one teamspawn):

 

Bump. To add on to the issues, whenever I try to run a map from Hammer in TF2, it gives me this:


CModelLoader::Map_IsValid: No such map '(map name)'
map load failed: (map name) not found or invalid

 

Are you trying to spawn as the Red team? I looked at your VMF, and see nothing wrong...

 

No, I was always sure to pick blue. Maybe I should just reinstall my Source SDK files in case something's wrong?
