Dark RP Floating Weapons ETC

For about 2 hours straight now, been trying to fix this error. Ive tried 3 different Darkrp versions and CSS a few times.
They just wont stop flying, also the banana’s/oranges, money printer. it wont fix. can someone help?

Are you sure you have the CS:S content installed? Usually that’s what causes this, as those are all models from CS:S.
