Im using this MOTOROLA rokr E8 from past one year.

Im using this MOTOROLA rokr E8 from past one year. i ve problem as of now. couple of days back i ve connected to my PC for music transfer. it wont connect as soon as i connect. i ve reconnect it for many times, at some cases it gets connected. this is happening from many days. to connect to my PC to phone i m using MOTO cable itself not anyother local one. but this is not the main trouble for me. like wise i was connecting in the same way just 2days back. it dint work for many times. then i kept quite. then after some time i noticed that my music playlist all empty. i cant see even my photos videos anything if go in to my Multimedia in my menu of the phone. i was thinking everything got formated but whn i go to the Office Tools-file manager its showing everything n even i can play each song. but wen i pree my music button its not showing
PLs help me out with this.

Thx
