Thanks for the reply Harry ..
Fictionwise replied earlier today and were not very complimentary about mobipocket to say the least! .. I'll cut and paste their reponses here ..
QUOTE [I apologize, since the Mobipocket interface changes, we cannot
change PIDs, this has to be done on the Mobipocket end. If you
would like you can contact the Mobipocket Support Forum and request
a PID removal. See link below:
http://www.mobipocket.com/forum/index.php?Language=
In the future, we strongly suggest that you purchase ebook formats
that do not place unreasonable restrictions on customers. For
example, if you have a device and/or computer that supports eReader
content, there are no such restrictions in the eReader format.
In addition, you get a 5% bonus rebate when purchasing Secure
eReader titles.
Please be sure to install eReader on your device first to make sure
you have a supported device:

Please note that additional device support will be announced soon
for eReader and by early 2009 it will have far broader platform
coverage than Mobipocket] END QUOTE
Have to say that I find it kind of worrying and wonder how much longer fictionwise will work with Mobipocket ..

PS I posted on mobipocket forums and by the time I'd posted it the PID had released so it's all set up now and working wonderfully

.. I'm still slightly concerned about the situation with fictionwise and mobipocket tho ..
