have you installed the SE PC Suite as well as the update application? The SEMCBOOT i think is the Sony Ericsson Memory Card Boot ROM/Flash memory. Pretty sure i had the same problem for my K800 and had to install the PC suite which in turn installs all the drivers you should need for the phone also.

Pm a link for the app please Jimlad.
doesnt the SEphone suite thing do the same ? i always just used that with my k800i sybced contacts with windows etc and could send texts
try it mate mate, it's bulk and clutter free makes the SE software look utter tripe!

How is everyone finding the battery life? I'm just so used to my w810i lasting .... erm, actually I dont even know how long it lasts, I don't need to pay attention to it. Must be 6-7-8 days? I really don't want to go back to 1.5 days battery life.
