I spoke with the wonderful Renderosity staff via phone a short while ago.  They are investigating the problem with orders showing as not completing, yet sending charges to the financial institution.

I'm sure they'll get everything sorted out soon.

In the meantime, I have 3 pending charges at my bank for $157.70 each (I tried twice to get the order to go and Support tried once.)  And no downloads available.  Will keep an eye on the situation after speaking with my bank later today.

WIll report back here and/or on my forum thread when it's all fixed. :)
