tranny messed up??

ok i bought a 93 civic and i blew out the clutch. but then i got it fixed right afterwards but now it's like the clutch doesn't engage fully. sometimes i'll be going and i'll slam the clutch pedal but the gear still grinds towards the middle of the shift. what's going on?? do you think it might have something to do with my friends grandfather messing with the pedal or do you think my trans is gonna blow on me?
