Problems to import logs to EventLog Analyzer v7

I setup a trial version of ELA v7 in a W7 Pro x64, w/4GB RAM. Installation went well but when tried to import a few archived Security event logs 64MB or 100MB from a Windows 2003 server, the status always shows "In Progress" but, nothing being imported, even wait for a few hours. Tried to import from a local folder and also tried from a ftp site with same result.

I have checked "C:\ManageEngine\EventLog\server\default\imported_files" and saw files are there, after using "Remote Host" with ftp info.

If I added a live host, ELA v7 has no problem to read event logs from that host and display the reports, just can't do importing. Please advise if I missed somethings Thanks.
