Andrew,
when transferring licenses from one pc to the next there is an order to do things.
on the old pc.
run the factory talk activacion tool, click on the rehost activations tab, click on the product to rehost, click on the rehost icon for the rehost code. write this code down!! failure to do so prevents you from going to the next step. also, from this point on, your old pc no longer has a license.
goto the ab website and goto the activations section.
enter in the host id of the new pc, product key, and the rehost code from the old pc. then get the license file as always.
without that information, you must contact your local distributor and discuss your situation.
you will need the product serial number, product code, when you bought the software, and 1 or 2 other pieces of
information.
hope this helps,
james
