i´ve got the same problem.. i am using a PIC452 and burned it with a prof-tool (chiplab from elnec) i set the dev-id to 0000 0000 and after trying to upload the mios, the same message returns... >:( then i set the id in mios-studio to 70 - it´s downloading. :D okay.. how ever - it´s running - but for me it´s not clear why there is a change of the ID?
