I'm not sure exactly but when I try to import a security event log the settings section under 'Report Type'  just continually shows 'in progress' and every few seconds the screen refreshes but it never seems to finish importing the file. Have left it running for a good 20 minutes and it's only a 9mb file so would have thought it would be fairly instant. Also the import time field is unpopulated.

I have tried running searches for event ID's which I know exist but get no results which would suggest the import is failing for some reason.

Any help much appreciated.
