I agree with kaotik, what is the point of opting in for the 6.4 branch if you are pushing updates to 7.0. It obviously is having major issues based on this forum. I for one would have paid to keep using the current 6.4 version with all the features vs upgrading to 7.0 and buying all the individual extensions for it and then trying to get it to work correctly. Maybe you should consider simply charging for the current 6.4 version with all the features since that version was pretty much perfect.
