My player has joined the ranks of the locked up Karmas. Same thing happened with my Creative Zen, only that player got around to locking up after several months instead of a couple of weeks.
I'm running firmware 1.25.
Sticking a paper clip into the infinitesimally small reset hole has proven no solution. I just get the startup screen, nothing more.
I'll be *so* glad when high-capacity solid state players become affordable.
