Solver returns no data - time domain simulation

Hello - please help. Solver returns no data - time domain simulation What is wrong with htis circuit - why do I get no data.

I was able to make one step forward by deleting the node "+15V", then the Time-Domain simulation would run. (I have no explanation for this).

Then, I increased the simulation time from 3 to 30 seconds. 3 cycles of voltage source V2 appeared.

Finally, I looked at the voltages on R2 and C2. The signals are small, probably not enough to switch the NAND gates. Try thinking about the value of R1.

Keep experimenting!
