Doesnt go into gear...Clutch, Tranny or other??

[LaunchHard]

Ok, so i read through previous threads before posting this and didnt see any similar issues.

Launched the car last night and everything felt fine on the way home. This morning im driving to class and halfway there im at a dead stop and cant get it into 1st. Take it out of second to get out of the intersection and get to my parking spot, park it and go to class. Back from class and now i cant get it into any gear. Goes through all gears normally when car is off, but none when its running. I started the car in first and held the clutch to the floor and it was moving forward.

The car has new slave and master with less than 1000 miles. Theres plenty of fluid and the car ran normally until this. The tranny has been tough shifting when i pound on it forever, so i dunno whats up. Im wanna know if its the clutch, tranny, both, or something else.

Thanks.
