Well, doesn't look like the list accepts attachments! So here is the Ogg: Re: ERROR: TR1: Jacobian singular at.
Can you try to use one of the other ones (pulse, file based, etc.)? I will look in more detail this evening.
The issue is likely due to the the rectangular voltage source, which has some known problem.
