You should not have to re install at all.

Be sure you haven't accidentally muted the track... I've had that happen on occasion.

Just the other day, I started to set up a vocal recording session. Replace the existing vox track with the final vox.... since I was recording live mic, I knew the speakers were off... so I put on the cans and hit playback to set levels..... nothing... no sound.... I saw the meters bouncing.... try a few things... nothing...

dang... the interface must have lost comm with the computer... it happens on occasion.... so a complete reboot and restart for computer and interface....

OK.. go again..... same thing.... ok, this should not be happening.... then.... I noticed that the cans were plugged into the laptop and NOT the DAW headphone amp...... the cans were in the wrong computer..... swapped the cans to the headphone amp... music!!!

silly stuff will get you.

If some of the tracks play, they should ALL play...so check the volume levels and the mute because it's not really evident that you have the tracks low or muted like in some DAW's.

I sometimes run BB/RB on an old, much slower, limited memory (compared to today's computers) laptop..... the one I mentioned above.... the programs still work just fine, however, loading the project, rendering the waves, and other processes take significantly longer on the lappy as compared to the studio DAW.

Give the folks at tech support a call. They are great and will help you sort out that issue in short order. They have assisted me and answered a few questions and issues I experienced.
