The log file says:
Error on line 9 : v3 in 0 pwl(1 m 0 1.001 m 1 2 m 1 2.001 m 0) ac 1
Unknown parameter "1.001"

You may not have blanks between value and unit. The correct pwl statement is
PWL(1m 0 1.001m 1 2m 1 2.001m 0)
I recommend you use the built-in editor to define the waveform of a source. This eleiminates erros of this kind. Simply right-klick the symbol of the source in the schematic:
