Problem with importing widows event logs .evtx or .evt

Hi,

Are there any extra steps necessary to import widows event logs *.evtx or *.evt?

I’ve got ELA build version 8.0 (upgraded from 7) installed on Windows Server 2003 , and when I try to import windows event logs nothing happens, No matter how long I will wait Report Type field is in “in progress”

I use fallowing options:
Choose Log Format: Windows EventLog
Time Interval: Run Once
Log Type: “I choose appropriate format”

I thought It may be because I use windows 2003 so I Installed ELA trial on Windows Server 2008R2 and try to import some windows logs and still have problem with importing, however this time I get the error message “Could not find the message file for the following event sources” and in Report Type field there’s “failed reports”.

I try to export and the import logs from servers using wevutil or just simply by clicking “Save All Events As” from Server Manager.

When I exported log to xml and imported them with fallowing options:
Choose Log Format: Automatically Identify
Time Interval: Import Once
Associate To Host: “I choose appropriate host”
Everything was OK

So are there any extra steps necessary to import widows event logs *.evtx or *.evt?

Best Regars
