Hi Michael-
Believe it or not, the biggest problem seems to be that I simply cannot get the files transferred. I have no issue setting up Joomla! from the control panel.
But I've also tried an installation into an empty directory, and also the automatic installation from Virtuemart.
One error I did receive was something to do with Joomla! needing to be -downgraded- (not the exact words) in order to run Virtuemart, but that was early on and I didn't see the message again.
I wish there weren't as many variations of installation... really, I'd love to see Virtuemart added to the control panel

Any help appreciated!
thanks,
Andrew
