calc2qif broken after upgrading to Windows 10

[Kash]

Thanks in advance for any help you can offer.

I've used calc2qif for many years to import transactions into Gnucash. 
It's worked flawlessly. I cannot be certain that the upgrade to Windows 
10 is causing the problem, but it's the only thing that's changed in my 
process and system.

When I run calc2qif an OpenOffice Basic code window opens with this 
error message:
OpenOffice 4.1.1
Inadmissible value or data type.
Data type mismatch.

and this line of code highlighted:
iYear = Year(DateValue(sDate))

The date format that I use is:
MM/DD/YYYY
and I have tried several variations on date format, all with the same 
result.

I have also tried to import an archived .csv file that worked in the 
past and get the same error.

Any ideas?
