Target error from Commit Flash write

I have been using LPCXpresso for a few months on two projects using LPC1754. Today we decided we needed a crystal. We added a 4.91 MHz crystal and I changed the constants in system_LPC17xx.c to multiply that up to 98304000. It worked fine the first time, but then when trying to download to flash again I get an error reported by target dialog box:

Details:
15: Target error from Commit Flash write
Flash erase or write operation aborted.

And the following MCU Debug Log:

(crt_emu_cm3_nxp) terminating on communication loss: Pipe has been closed by GDB.

If I use another JTAG tool to erase the flash first, then flash downloading succeeds once.

I notice in the log it says "assumed clock: 240.0MHz". That is not right. Is there a way to overide this? Any other solution or workaround? Please help.

Thank you, it is working now. I set the vector catch option to true and it worked. The funny thing is, I set it back to false for verification and it still worked.

Setting "Vector catch" to true works. However, there is another field in the target's debug configuration named "Crystal (XTAL) frequency and PLL value" that sounds like it would be applicable in situation where the XTAL and PLL frequencies are changed. CodeRedSupport, where is the documentation for this configuration option? I've searched the LPCXpresso help and getting started guide.

Thank you.
