Package diveMove readTDR problem

I am trying to read my TDR data into R using the readTDR function for the
diveMove package.

seal <- readTDR("file location and name here", dateCol=1, depthCol=3,
speed=FALSE, subsamp=1, concurrentCols=4:5)

But I keep getting the following error:

Error: all(!is.na(time)) is not TRUE

All my columns to have values in them (there are no empty records)

The manual and vignette of the package diveMove doesnt give a proper
description of how to read data into R. It only describes how to access the
data in the system file that comes with the package.
What am I doing wrong?

It's hard to answer this without a reproducible example, and it's
generally harder to get answers about less-used/more specialized
packages.  I'm going to guess that at least some of your dates are
not in the same format as specified (from the manual page: 
default is "%d/%m/%Y %H:%M:%S" --
you can change this with the 'dtformat' argument).

  You shouldn't need to specify arguments to the function that
are the same as the defaults: I would expect that

seal <- readTDR("file location and name here", 
    subsamp=1, concurrentCols=4:5)

would work equally well (or poorly ...)

"%d/%m/%Y %H:%M:%S"
