Error Importing EnterpriseTrack.swi

Hi all,

When I try to import the EnterpriseTrack.swi file on a new Enterprise Track 16.1 installation I get the following error:

IMPORTING: /, found the following problem while validating queries for engine [utils/visual_mining/cache]

Error validating Queries for engine cache: The validation of query "findOld" failed: Cannot parse '1990/01/01' into a valid datetime value. Either the date is not valid or it is not in one of the following formats:

'yyyy/MM/dd'

'yyyy/MM/dd hh:mm a' Expression [daterange(date("1990/01/01")^, SubmitDate, SubmitDate_to_d)]

Does anybody experienced the same error? What does it mean?

Many thanks,
