Query: Cardscan WAS great until Dynmo bought them

I bought the Cardscan V7 a year ago, now I tried to buy upgrade parts. the Dynmo web site is so poor, they do not service it at all. Customer support and feedback is an afterthought.I bought the Blackberry connector so that my scanned cards would go into my Blackberry directly without Outlook. The web site crashed many times trying to even look at the product, then after my trying 10 different routes to buy it, it finally allowed me to view the product for sale.once I bought it, it had no serial number and here 3 days later, there is still no serial number for the software. I cannot use it or install it.IMHO Dynamo bought a good product and company and is driving it into a poor product. they use the normal redirect all customer support to a user forum rather than answer their own problems. Buy at your own risk, as they will drop you on the floor flat the day after they have your money.
