I've recently installed on my Mio P550 pda signwise professional v2.51. I've reseted it and now it asks me for a password. I tried everything, every pass that I ever used in my life but no succes. It requires a pass also when I try to use active sync from my desktop pc. Is there any way to find this pass or at least to bring my pda to a factory state (delete everything but windows)? Any help would be appreciated.
