Sorry, that is just wildly inaccurate. Since the only recent release was three days ago, I must assume that you are talking about that. Leaving aside the (pretty important) fact that this is a development release and I have put it out with a big disclaimer that we are still working on the last bugs, I have problems finding what you are talking about in the forums.
After I have put up the latest release, there were 7 threads posted. Two are about a minor PHP warning (quite common with development software). One where people have not understood recent changes, which I explained. One was for a payment processor - which is well known to cause problems (and which we have been trying to integrate for half a year now) and another one for a component integration that is scheduled for the upcoming stable release. One was about a bugfix that didn't work out for this user - and I have since requested further details on this. And the last one was of a kind user who provided us with a custom Spanish translation.
Sorry, but is that what you call "numerous reports of bugs, incompatibility, issues with connections, blank pages, failed processing of invoices"? Or were those your personal experiences?

As for the rather grave accusations - I have yet to hear of a case where invoices or payments are "lost". The worst thing that can happen (if I make the right connection about which of the recent threads you posted in our forum) is that a payment notification comes in and is not parsed correctly (or understood at all). If that happens, there are tools to fix that immediate issue (manually clearing the invoice in the user account). The next step of course is to figure out where it went wrong. Since the AEC logs a lot of data, the first step is to have a look there. In most cases, its a setup issue with the payment processor (for example - if you did not set your PayPal account to automatically accept payments without your consent). If you really are using a processor like Clickbank (the recent reports were about that), I would be glad (and have requested) to get any further details that help me fix the situation. I have detailed the problems with Clickbank on a number of occasions (they don't really like you to handle your own business, but would rather have everything on their site... which makes integration a hit and miss if you factor in that their documentation is not only inaccurate and self-contradictory, there is also TWO of them - which in turn contradict each other!) and while it always and again and again seems like we are close to getting it to work... well, I'm tired of making the promise that it will work soon. I'm trying to get it to work - And that is all I have claimed about that for a crushing long time now.

Apart from that - I have now put up a big RED box at the top of the forum saying that its a community forum, NOT the place to get professional support. If you have problems paying a small fee to get help when you obviously need it (the majority - by far - of users can use it right away without encountering any of the problems you have talked about), I'm not sure you have understood what this is really about. Also: I don't sell software (and I never get tired of saying that).
