I'm wondering if errors like the oft-repeated "object not found" issues in 4.4.1 and the log viewer problems such as the below have been identified and addressed in 4.4.5?

InnerException: Element 'LogProperties' was not found. Line 1, position 2.
FileName:
FileLineNumber: 0
FileColumnNumber: 0
Method: System.Xml.XmlReader.ReadStartElement
StackTrace:
