Ok, so this thread is seriously unjustified at this point. Ukyo is clearly having difficulties delivering. But it does not justify a scam accusation so long as he appears to be working on the issue....
Really loved your explanation but it SHOULD come from Ukyo, yours is only a guess. Might be the correct one, might be not.
Ukyo has got a business that not only runs on a technical note, it also consists on telling ALL his customers (a note on the website perhaps???) about what´s going on. Feels like we´re alpha testing here.
I´ve worked in software development too and this is a very common claim, "it´s not that easy to fix" and whether I do believe is not an easy fix, I have to remind again, this is only a part of his business.
Example: you call weexchange on the phone and the person answering could give you a pre-scripted answer to the query (which is now a common one). Seriously, that takes 5 minutes to think and resolve and will leave people a bit more confident.
