Welcome in the forum, rob.
Although I do not know if it will cure your issue, I would recommend to update to Creator 3.3 CP3 which is the actual latest version. Do not forget to update your project's components as well.
Can you send us the series of commands and the output for the commands that you executed before performing "Program" command.
Recently I encountered the same problem. I cannot acquire device (PSoC4) in SWD mode with neither Miniprog3 or KitProg. Additionally for Miniprog3 I have to choose a different type of connector. I use a 5-pin connector. But to power up the processor I have to use the "SetProtocolConnector 1" command, despite the fact that psoc_programmer_cli.pdf says that for SWD mode parameters are
0 - 5-pin connector
1 - 10-pin connector
With GUI applications all is programmed correctly with the Miniprog3 or KitProg

I'm with the same situation that I can DAP_Acquire and I can read Flash information but Program always returns "Not in ISSP Mode"
Is there a solution to this issue because I see the same when programing with the Psoc GUI there is no problem but thru CLI interface the programmer always return: Device is not in ISSP mode
See the different modes of the Kitprog in its manual. Watch the LED. Try pressing Reset button on Kitprog for more than 5s.
have you checked if your SWD lines are high by default? You may have to add a pullup resistor on swdclk and swdio. I am not certain what values of resistor to use but ARM suggests 100k ohms.
