Issue importing dates with CSV

Hi,

I'm trying to do a mass import of sessions via csv, which seems to go fine until I add the a column to import the Purchase date, at which time RDM complains:

Unexpected error has occurred. Please check the execution log.


CSV Contents:

Host,MetaInformation\OS,MetaInformation\ServiceTag,MetaInformation\SerialNumber,MetaInformation\PurchaseDate
BLHPOS4,Microsoft Windows 7 Professional,10AHCTO1WW,PC069F6N,2015-08-07



The date format appears to be correct according to the help:

MetaInformation\PurchaseDate
Purchase date in a ISO8601 format, i.e. yyyy-mm-dd


[/table]


Error text from the execution log below:

And as I mentioned, as soon as I pull out the column for date the data imports perfectly. Any ideas?
