X10 SonyEricsson Sync failed

[#1]

Hello,

I can't sync my mobile with my SE account. I don't know why, but this problem is for 2 days. Yesterday after half hour of retry I synchronized my telephone after telephone restart, but now again the. I tried to restart my phone, but nothing changed.

How to solve that problem.

Thanks in advance
