Just last night I had this problem - tried to reprogram the PLL, ended up with board that gave:
15: Target error from Commit Flash write
Tried the Vector Catch option in the article suggested by Zero. Clearly my board fell into the ' image contains code that sets the MCU clocks up "incorrectly"' category. I believe vector catch means the debugger traps the target on the ARM hardware vectors (specifically Reset in this case), which stops the ARM executing the bad clock code. Then you can re-preprogram the flash. Board now working.
Funnily enough, before that, I tried another board, and got the "Bad ACK returned from status - wire error." message. This is what it sez... I replaced the loom that connects the LPC-Link board to the target, and that problem was solved, too.
Hope that helps?
