If you bought it from this guy then you are screwed. If you need the software start looking for another seller, this one will most likely never answer since he was online today and chose to ignore you. That's exactly what the trust system was made for.
Here's a rhyme for you about this guy that did not care the trust was red, received no item, started to get mad, looked for support, made his own thread, when the answers came punched himself in the head.
