Hi MrMedia,
Thanks for your feedback. The message “retrieving” is a generic term used to denote the current progress, whether exporting or downloading data. From a user perspective it doesn’t matter whether the system is specifically downloading or exporting as this is all automatically handled and processed in chronological order.
The error you are getting seems to suggest that the downloaded file on disk is corrupted somehow – perhaps due to lack of disk space or internet disconnection issue? In these cases, the system will try to retrieve the data again. If you receive any errors during your export you should regenerate it just in case there were unrecoverable errors. If not, any invalid/missing data will be omitted from the final export.
If you need more information about the downloading process, please have a look at this discussion:

Thanks.
