I am working with the LPC11xx, and was testing the release version of the build, which enables the WDT. However, now that the WDT is enabled in the code residing in flash, I cannot reconnect with the debugger (using LPC-link) in order to reprogram the flash. I get the following error:

Error launching Release\<application>.axf
03: Failed on chip setup: Et: Flash driver not ready

Is there any way I can regain access via the debugger now?
Thanks.

Start bootloader - tie ISP pin to GND and reboot MCU.

You can mass erase before programming too. Works for me.
