When I look at an entity and type "getscale" in F1 for any entity all I get is "Error: That entity is not tracked by Entity Scale Manager" there for I cant even scale it.

If you havent scaled an entity, there is no point in running that command, the scale is 1.0. That won't prevent you from scaling the entity.

By the way, since you mentioned F1, there is a client command called scale, so you can't use the "scale" command in F1, you have to use /scale in chat.
