HUD Problems

ok I just got my laptop back from being repaired t find they put a new hard drive ingto the dthing (very angry about that >=|)so i’ve had to reinstall steam and all my games
when i started up gmod earlyer today it updated and then loaded like usual but when i got into a game i had letters instead of weapon icons and i had a Q for a cross hair
hope i’m not the only person with this bug =’(
and if i’m not is there a way of fixing it
