converting from Keepass2 using converter [Need 1Password 7]

In my confusion after arriving for work today, I renamed that file in error. Either I'm missing a step or...

C:\temp\mrc-converter-suite>perl convert.pl -v keepass2 pm_export.json
Negative repeat count does nothing at
C:/Strawberry/perl/vendor/lib/XML/Parser/Expat.pm line 372 (#1)
(W numeric) You tried to execute the
x repetition operator fewer than 0
times, which doesn't make sense.
