Transient analys cuts off at .45 sec

[Joe1123]

My transient analysis stops at .45 seconds, and I can't get it to go beyond that.  I have my TSTOP set to someting beyond that (1sec, 2 sec, etc), I have used a variety of TSTEP and TMAX values along with the automatic ones, and I have set the max number of points to 1280000000.  

Is there some other setting I am not finding under the transient setup?

Also, this is using Multisim 14.0...

I am also getting the error "Transient time point calculation did not converge"

I have attached the schematic.  If I remove C5 & C6, it simulates as long as I want. The capacitors seem to be causing the error. 

Any help is appreciated!

Alright, good talk...I ultimately used the SPICE troubleshooting guide off intusoft.com, and relaxed the GMIN.  It seems kind of like a band-aid fix, but at least it simulates now.
