Are you using the prepare sector command before u erase/write them? 
What area in flash are u trying to write over? Just curious.

As long as u call the IAP function passing in the frequency value of 
the physical crystal, I think PLLs shouldn't matter...enabled or 
disabled. I have my PLL enabled running @60Mhz now on a 12MHz Xtal, 
and I can call IAP to write flash without trouble using 12Mhz as the 
frequency value. 

Interrupt events can mess the IAP process. Hopefully that's the only 
firmware bug to worry about.
