NonConf.SysDate - Crystal Report Errors V6.1

I am trying to run a report based on a date calculation (ie. three days
ago... last 15 days..etc.) using the NonConf.SysDate field in Crystal
Reports. Occasionally it will run, but more other times it will error
out with a message similar to: "Column Description in NonConf has value
exceeding it max length or precision"

I read somewhere that this is a known problem with Progress and Crystal
Reports. That the date is not always returned from Progress in the
format that Crystal expects it in.

Has anyone had this problem and found a way around it???
