ERROR -- Convergence problem in transient bias point calculation
hello, I have implemented the circuit shown in the image attached with this post. When i run the circuit it gives me and error i.e.
"ERROR -- Convergence problem in transient bias point calculation".
The simulation window shows these messages:

Re: ERROR -- Convergence problem in transient bias point calculation
Are you joking? Obviously the schematic circuit doesn't belong to the netlist which has e.g. 4 transistors and three voltage sources.
