This is not a trainer issue. Not a horse issue either as it happened to me before i got the horse. Also, it is a big issue, since you cant progress the game without the use of crossblade and later the hook and teleporter stuff.
Empty hand/unable to select crossblade or anything else for a secondary weapon, can easily be fixed, although your save games will be lost

Correct me if I'm wrong but the earlier mentioned fix (chaos form - enter it and press + or - on your numpad) should solve the problem of not being able to equip anything.
As for the "empty hand" problem, are you saying that the only way to fix it is to start over the game on a new save?
Thanks for the info anyhow!
