Thanks for the story, I am doing exactly the same as you, setting up business and struggling to afford to be legitimate with the price of Adobe software.
I have found people selling it on ebay even cheaper claiming to be Adobe resellers, with UK versions for sale at between £800-£900 pounds and even the master collection for just over £1000. I emailed them to see if I could register with Adobe, no answer though.
I am reassured by your tale, but can you register it with Adobe?
