How to read old .raw version and still converge?

edit

I am loading a v30.0 .raw file into v34.0 through the API using readrawversion().

The window outputs the details of each step of the conversion from v30.0 to v34.0. After reaching v34.0 I receive errors pertaining to the items listed below. The model then fails to converge by a significant margin. Questions are:

1. Is it possible to avoid the conversion altogether? This would be ideal.

2. During the conversion, I believe it causes a change to default voltage values (I caught this reading a separate forum post). Is it possible to avoid this reset?

Error items below.

A number of generators: Error: Invalid ZSORCE reactance: .00000; set to 1.00000 (002230)
