Most likely you do not need to call StartTransaction.

My guess is that you simply have forgotten to set the IB_Connection and
IB_Transaction properties of your query (and you may check the
IB_Connection property of the IB_Transaction as well). I haven't got any
zip-program installed on this machine, and do not have time to move it to
my other machine in my office, so you have to check this yourself.

HTH,
