BF4 pc sucks (not really) but keep getting kicked?

Decide to go from Xbox BF4 to pc BF4. Join my favourite map operation locker. Spawn in and then insta killed for having "M320 HE" Ok sure, take "M320 HE" out of my load out. Spawn in, insta killed and then kicked. Join other operation locker server. Same happens.

What am I doing wrong?? Why am I getting kicked, it said the take the grenade launcher out of my load out so I did and I still can't play What is happening!! Maybe my grenade but I can't change it to anything, I even joined an "all weapons" server but still get kicked.

What do I do? This is a completely new account and I can't even play?
