bqstudio does not recognize the bq34z100evm boad

I'm trying to run bqstudio version 1.3.42 through the EV2300 version 3.1m and communicate with a bq34z1xxEVM board.  When I invoke the studio I get this message:

I have connected using the 0100_0_15-bq34z100G1.bqz and the 0100_0_16-bq34z100G1.bqz targets but I'm getting flaky results when I try to change data memory values.  The software "allows" me to change a value but when I try to write to flash the value does not get written.  I cannot use the IC in it's present configuration.  Does anyone have a clue as to what to do to correct this problem?

Thanks!
