The "Auction Factory gpl club vesion" is a native Joomla 1.5 product where the support is limited only on the forum, since the GPL version addresses mostly to developers, while for the Joomla Community we are offering other software versions, with extended support on ticket system and even installations, etc.
Also you wanted to have extended features like templates, payment processing, upgrade script, etc. (for less money) which are only available in other versions, not the gpl club version, fact which is been very clearly explained on our pages.
Was installed on Joomla 1.0 and 1.5 without any problem. Of course, it is just in Beta and some important tools has to be improved (email forms, gmap, and esthetically details we can not modify easily), but after intensive tests, my web site based on this soft is 80% on ! Great job.
