Sorry to hear you're having trouble connecting a debug session. First, please provide the revision of your LPCXpresso installation.
Next, search through the task list and kill off any arm-none-eabi-gdb, crt_emu_cm_redlink, or redlinkserv processes you might see. Then, boot the LPC4357 into the ISP using the push buttons on the board, and retry the connection.
In the event this fails, please copy the contents of your console debug log, and post it in your response.
Regards,
LPCXpresso Support
