Dear Arya,
I suggest to add a new archive in the Archives table and in the Server settings.
This archive should not be default. Set archive mask for channels that will be written in the archive.
Thank you for the thread, moved it down the list and it helped (Server-> Archive).
In version 5 reports could be viewed and exported in CSV format! Is it not the option anymore in 6.2.1 version?
When trying to open XML file it says XML file does not appear to have any style information.
