After updating from OS 4.6 to OS 5.0, I can no longer use Desktop Manager to sync my phone. It starts then stops and says that there was a "Unknow Error". I also have 2 log files that will not clear if I try to delete my log file.
This is one of them, I thought it was strange because of the date.

Name: System
GUID: 97c9f5f641d25e5f

JVM:INFOp=********,a='5.0.0.822',o='5.2.0.76',h=84 000e07

I removed my PIN.
