Hi I am considering buying “EZ drummer 2 from a popular Music gear website It seems to be cheeper BUT it is just a download-able version If I buy your Toontrack’s EZ Drummer 2 from this music gear’s website and download it and in a month my computer crashes or I get a new computer how can I reload EZ Drummer without a install CD? (Because I don’t get one when I just “download” it from you? And most important not have to PAY for a software I already paid for? TIM
